The study of natural sciences was forever changed when the English polymath Robert Hooke looked into his microscope for the first time and examined a piece of cork. He saw that the cork was composed of many small compartments, which he named “cells” after the chambers of monastery monks. Since then, living tissues have been understood to be compartmentalized, an understanding later complemented by discoveries regarding atomic structure, biomolecules, and how the latter are the building blocks of cells. Thus, molecular and cell biology can be defined as the study of the biomolecules necessary to build and sustain the cells that make up living organisms, and how a typical cell functions.
Molecular and cellular biology is the cornerstone of the basic and clinical sciences in medical education. On this subject rests the ability to understand more-complex concepts of physiology, histology, embryology, and anatomy, as well as how normal processes can go awry and cause illness. As the medical profession progressively focuses more on the molecular aspects of disease, it’s imperative for the physician to have a good comprehension of biomolecules and the cellular machinery, allowing them to understand the many changes and interventions that are yet to come.
In this course, the student will be exposed to the basics of biomolecules and the most important principles of cellular functioning, including the structure of cells, the cell cycle, cell division, and gene expression.

Great material easy to learn good pictures …..thank you so much
Simply explained. Can't emphasize more how important this is
I like the immediate quiz and 'notes' format after each video.
The information is presented in a way that is easy to understand! Thank you ????

very confused and not organized I feel like its too messy and i can't catch the points
The analogy of the central dogma is the best explanation I've ever heard!!

A great summary and introduction to an important but sometimes confusing topic. The questions following the mini lectures sometimes seemed out of sink, covered in a later lecture, etc. For students using this as a key resource, it is essential they understand that using the suggested textbooks and answering all the questions is necessary if preparing of licensing exams, etc.
I appreciate the approach to clear concepts and road map to the subject matter.
This subject was amazing to learn, and Georgina makes it easy to understand, so I could say that really loved this course, thank you.
Well structured and comprehensible. Ms Georgina Cornwall makes pleasant pauses between sentences, speaks clearly and explains so that it is easy to follow. The questions afterwards are also very helpful.
I am enjoying the lectures. I have two, very minor issues. 1. They are a bit too "granular". Some are so short as to prevent you from digesting the material as it is presented. 2. On several occasions, the questions were not covered in that segment but rather in the next!
Topic is not comparing the topics from previous topics in the table form. Then students will remembered
As a retired physician, still professing clinical subjects at a medical school, it is great to have an opportunity to revisit topics last studied in depth in the 1970s! It is presented in clear and digestible aliquots and in a logical sequence by qualified lecturers.
The teaching is basic and does not represent material tested on USMLE exams. The concepts are taught by an instructor unfamiliar with the actual exam. Technically, questions pop up in the middle of a sentence and sometimes before the subject matter tested was mentioned.
An excellent and detailed description of each phase with emphases on correct language.
Ms Cornwall presentations hard to understand with no clear imaging and orientation of the slides
Concise and easy to understand content. Thank you Dr.Georgina!
Great review for practicing physicians who have been out of med school for some time.
It is too simple like introductory biology. We need more advanced molecular biology
lack of information no explanation ,its like you are reading headings. and the quiz questions are poorly made.
Great way to remember the three portions of the ribosome!
I, really, liked ALL of Dr. Cornwall's lectures, but did NOT find time to rate them! I am, still, trying to put it all together because molecular biology is my most difficult subject, but Dr. Cornwall put together much that I knew -- and I am far better off than beforehand! I, definitely, now understand as much as any medical student ought to about molecular biology -- and thus, I am glad that I made notes the whole way, giving me paperwork to re-think all that Dr. Cornwall taught me! Thus, I wish Dr. Cornwall the best and am grateful! :)
Breaks concepts down easily and love the review questions. Helps solidify learning.
Thank you, Dt. Cornwall, for this chapter!!! It was very useful and finally, with the help of your tips, mnemonic and your awesome teaching style, I could understand the process!
very new insight to explain macronutrient and fruit for thought
Really liked Enough chemistry to explain it / not more Shows that she is passonate about the subject
Georgia Cornwall has done a conscientious job at teaching molecular and cellular biology -- and I enjoy it daily! :)
There are mistakes in the video and they make the material more confusing than it should be.
A very concise content with relevant short videos and quizzes. Great program
The explanation are cleared. However, they are not included many scientific terms and scientific details that necessary to well understand the content and to do well in the MCAT exam. In other words the content of that lecture are too simple for MCAT students.
I understood very well the topics. I learned things I didn't before in school
I love cell biology and this classes are amazing. Thank you
Thank you so much It was great I enjoyed watching these videos
How can the process of charging of tRNA be explained if the concept of tRNA has not been presented? What tRNA does and then how it's charged. I am loosing too much time googling stuff. Maybe it has been presented, but it's not part of this playlist, which should be complete.
Very good teaching. Very good images and very good explanation.
This explanation was not clear at all. I had to research a lot of information elsewhere to understand the concepts presented. This is the exact opposite of what is to be expected of something that should make students life easier.
yummye yummy yumme yom? yommer yom yom yom; yom yom yom.
Simplified and we'll explained. The teacher knows her topics well and explains in a simple way for all to understand.
very good knowledge gained. Learnt a lot about RNA and DNA and messenger RNA
very clear , and natural. High yield, very in depth. Great knowledge gained
FINALLY! I get replicated homologous chromosomes! Professor Cornwall cleared up a haze I had about this point for years in 3 seconds. I don't understand why there are not more people who emphasis the difference between homologous and replicated homologous chromosomes. Thank you Professor Cornwall.
The concepts mentioned in this lecture are very confusing and poorly explained. She made no effort to clarify the meaning of homeodomain, homeoprotein, and other such concepts. Also, she seems very unsure of what she is teaching and the speed is too fast to properly retain the information.
It was very comprehensive and I loved how easy it was to understand
I appreciate these refresher and very well-explained building lectures.
The content of the lecture/presentation is excellent. Has somebody else prepared the material?
in depth knowledge on DNA splicing, ecor 1 and so the base pairs want to stick together and then ligase comes along to stick together the backbones, the phosphate-sugar backbones. Here you can see how the two pieces come together and now we have a recombinant DNA molecule. Again, we are generally looking at a circular chromosome and a foreign piece of DNA being inserted into that circular chromosome and so we'll see two ends of sticky ends and insertion of that sequence.
This lecture gave me a brief knowledge on how rDNA is made.
Easy to understand I like that subject Clear explanations relevant for my dream job
I liked the lecture. It was clear and concise. I liked it better if the lecturer used more visuals of techniques.
Very informative and detailed. It allows you to understand the concepts on a fundamental level.
I liked this lecture and I also like this teacher. I just sometimes find the explanations a little be confusing.
A student could do this lecture and it would be easier to understand. we expect better lectures from professors.
Very good lecture! Interesting clinical correlation (celiac disease). Thank you!
I'm really enjoying Dr. Cornwall lectures, I love the way she explains things!
Clearly presented talks and material. Very useful for undergraduate students.
Like the step-by-step discussion. Make it easier for me.
Covered a vast portion of the basics that are the most important part of the foundation. The structure of the course is phenomenal and the way it is carried out is engaging and made extremely interesting. Concepts are crystal clear after going through the whole course. Thank you so much, psyched to have found this! I only wish this material was downloadable for future reference. Hoping it could be. Thanks again! This has cleared the slightest doubts Ive ever had, hoping to have many more courses conducted by Georgina Cornwall.
not very engaging with the viewer, and it could be even more dynamic
This topic is OVERLY simplified. It needs more in-depth explaination, which she claimed to offer later. But this brief section creates even more confusion... Maybe it is better to do a PROPER introduction, or just cut this one out... Also, she herself seems to be unsure and confused. I am not sure what her profession is, but DNA doesn't seem to be a topic, which she should lecture on... In the middle of the video she just blanked, and kind of skipped on some points... (That's not the first time or first lecture that she does that...) P.S. The powerpoint is also not accurate... The coding strand around 0:52 is indicated as template strand... This lecture is quite disappointing, and frankly, a very low quality compare to other Lecturio's lectures.
More organization is needed to explain this lecture because is an important part of the DNA synthesis.
I love her course. She explains in a very understandable way.
Content is spot on. And quizzes at the end of each videos are very helpful. Hope Georgina used a cursor or infra red light to point exactly what she was talking similar to other lecturers from other videos. An animated video clip of how each or some of the topics would be very useful.
Hello, I love supporting women in science and education, etc. I also will share my honest opinion to improve the educational site. This lecturer, while alright, is not the best you could get for Lecturio students. Her constant glancing over her notes is distracting and she is not very well articulated. Even though she is Ph.D., she has not digested her lecturing materials to the master's level. It is very unfortunate that she lectures on one of the most important subjects within your platform. Why you chose her? For the sake of diversity and involvement? I am sure there are much better and knowledgeable lady lecturers. Did not you see the disengagement and flaw after a couple of her lectures? Was she so cheap?
I am no longer scared of metabolic pathways. thank you so much.
I liked to much because maintain the point of what are she explaining the theme with clarity and didactic form about the macromolecules of life the first principle to begin the content of the nature of the Body , systems organs ,tissues and cells.
Incredible Easy to follow the class The professor had my attention all the class
Biochemistry by Georgina Cornwall is not good at all, she reads all the time and she doesn't even know what to talk about.
She didn't talk about the template strand. the prof fumbled with the coding strand and im actually confused if the coding strand, or the tremplate strand matches the sequence of the mRNA. She definitely seems disorganized. It didn't flow at all.
I liked these explanations, but if you are a college student this may not be for you
Very condensed, but a well-taught lecture. I love the teacher´s style.
Nice explanation, very useful, easy to follow. very useful reminder of basics.
SHE IS NOT CONFIDENT IN TEACHING AND RUINS THE MOOD OF LEARNING
I could not understand it good at that in my university college friends
one of the best teacher ..yo mam ............really enjoyed it
i liked the details and visualization. should have been there more mobility in the slides tho.
Need to explain better as it is very complicated and confuses us even more than we were before
Nice course very complete in every sense, I like it, keep like that.
Awesome overview! Thank you! Particularly liked the gluten example. Also graphics were good - will stick in my brain longer.
Lesson was so fast and not understandable .Lecturer should have gone from easy points to harder points.She could not make it easier this topic for me .She did not use her hand at all during the lesson.This is so lazy way for giving a lesson and unproffesional.
I dont know if its the diagram or what the doctor is saying but i just cant understand the MAP kinase and the GEF and everything else afterwards
Explica las cosas super simples y puntuales, se memoriza rapido de esa manera
she reads from her notes too much, strikes me as someone who does not have a firm grasp on what she is teaching.
Very clear and succinct. May have gone a bit too fast, but that's always manageable
I recommend include the cc out of slides screen, the letters do not allow to watch the information
adioasd oiaj doias ds dioas jdoias jdoas djoi asdjoia sd o
Basic topics which i had difficulties in understanding has been well explained and now I have fixed the knowledge :) Suggestion: it's hard to cover the extremely fast growing biotechnology topic but I guess "omics" would be good to add
I really liked it and enjoyed Dr Cornwall'ss explanation. The only issue was that the video slowed at some point.
Despite the mishaps, I thought the information was understandable. Especially the ending when she connected Trp and Lac operons with repressible and inducible.
I saw many times the video, take notes but I don't understand at all this video; think is some confusing :(
Hi I appretiate her lectures about biochemistry, l hope the following lectures would offer me more interesting information.
lecturer is breathing heavily that is kind of distracting. I don't know if it is because she is wearing the mic very close. lessons were nice tho.
I am in my first semester of Bachelor of Science in Biomedicine in Switzerland and the courses are helping me a lot. I can watch your videos after a whole day of studying and I am always having fun! I get a great overview and know what the most important concepts are. I also have no issues remembering what I learn here. Thanks a lot! I learn new things while answering the quiz questions as well, they are smartly structured and help a lot as well.
Love your lectures, Professor. It is helping me a lot reviewing Biology as It's been years since my basic science years.
this is a good lecture i really understand a lot of thing i haven't know before tysm
Although the whole course (and actually the whole of Lecturio) is absolutely wonderful, I enjoyed this lecture with Dr. Cornwall so thoroughly, that it felt like time was passing by rapidly! Before I knew it, the lecture was over and I had learned so much! Dr. Cornwall has a way of explaining things that makes you understand is the matter longterm and makes you curious to look deeper into it. Thank you very much for everything! Eileen Dara Greetings from Belgium
simply explained so well understood, very well done. lots of info but concise
I select leturio because its teaching method is very awesome knowledge base Usmle type based
Great concise videos covering salient points in biotech. Most of material is well presented though some concepts I've had to supplement with other sources to fully understand. Overall, great useful series. Thank-you Dr. Cornwall!
It is a good introduction for the following classes. It's not confusing, but more information could be added
Liked it too much as it's so easy to understand ????...but cannot afford premium ????
Dr. Cornwall is awesome! Her lecture are clear and concise. She makes the material so much more digestible.
Dr. Cornwall is fantastic! The biotechnology series helped me SO MUCH going into lecture.
She keeps it short and simple. Great work in this video. It's great prep before going into a lecture!
TOO SIMPLIFIED AND IT SEEMS LIKE THE LECTURER WASN'T WELL-PREPARED FOR THE LECTURE KEEP SAYING NONSENSICAL WORDS. I AM REALLY FURIOUS AND FRUSTRATED LISTENING TO HER LECTURE.
Me agrada como explica las cosas la Dra, creo que lo hace que sea entendible de forma sencilla para cualquiera
La Dra explica muy bien y de manera sencilla, algo que me gustó mucho son las analogías que utiliza para dejar claras las cosas, creo que eso lo facilita
I belive she is very clear and resume complicated topics nicely.
I suppose it depends on your learning style. That is, most of the medical students I've spoken to, appreciate concise and coherent lectures - Unfortunately, in my personal opinion, this micro-lecture lacked the fundamental high concentration of information that most of us are looking for - to take notes, and practice the spaced repetition model. Instead, her speaking pace, and vocal expression are slightly too fast and the way in which she attempts to outline a basic idea isn't linear in nature which leads the viewer wanting to know more, while simultaneously trying to ignore the off-topic rants. Note: Clearly, she's qualified to teach - however, valid of a point that may be, doesn't mean she has the practical communication skills to do so. Therefore, this is not a question of intelligence, rather - communication and linguistic expression. There will certainly people who prefer this method, I however, can not recommend.
I had many doubts but with the lection, I improved much better
The lectures seem to cover all the necessary contents, but it’s often difficult to understand the topic until I go over the video again for several times.
This lecture clearly points out the differences between prokaryotic and eukaryotic cells in protein synthesis. It would be helpful for those who wish to briefly know how proteins are formed in each type of cell.
It is a good explanation for a complex topic, with only the most important
complicated topic but I think I got it, though the Tyrosine kinase itself is a bit complex
I like the format - the lectures are "short and sweet". The lecturer is reasonable easy to listen to. Perhaps it is just because this is a foundation course, but it does feel this material may not be in-depth enough for USMLE step 1. (Or perhaps because it's re-used for non-USMLE students?). The questions are just "okay". There are a few errors, and a couple questions could be worded better. It also seems that some of these questions are testing material that seems only marginally important, and may not be very "high-yield". I wish there was an option to flag review questions to not be included in the "spaced repetition". The "spaced repetition" idea should be for memorizing the most important details, and I don't really want to be memorizing questions that I think are of little importance, incorrect, or poorly worded. (It'd also be a good way your you at Lecturio to decide which questions should be revised - if many people flag it as "don't review again", the question probably needs revision.)
not clear voice . . . . . . . . . . comparatively worse than other videos, others are good.
As I stated in prior lessons, Dr. Cornwall is such of an amazing instructor!!! She makes easy to understand heavy contents
the instructor is very clear and is easy to follow
Dr. Cornwall did a very great job with this.. The big picture simplified everything and made studying into little details easy.
very didactic I really enjoy Dr. Cornwall lectures, definitely Lecturio was the best addition to my preparation
el contenido esta muy bueno, solo que la traducción tiene falencias y dificulta entender los conceptos adecuadamente.
Everything is confusing. The diagrams and what she was saying didnt allign. ALso she never gave the answer to the number of chromosomes in each stage of meiosis and mitosis
the explanation is complicated it could be simplified more better
Very well taught, good refresher. The high yield points are in there too.
Very well explained. Would have appreciated had the lecture been a bit more comprehensive on certain topics, like in DNA replication and also a dynamic step by step diagram of the process would have been better to understand.
The lectures are great... But I just feel like they are too expansive... Not very suitable for a dedicated study period
It is very concise but it provides enough information. I am very satisfied with Lecturio because this course and Biochemistry are exactly what i was looking for.
The video episodes are way too short, need to go back and start over every 3-4 minutes. I think there should be a option to view the topic in one full video. Otherwise the subjects are well covered in an understandable manner. Many thanks
The way of teaching of Georgina is really impresive, i understanded everything. The best classes ever.
Very comprehensive lecture . It' s clear and simple. Thank you for your work .
Great Great great great great great great great great great
O really like it , because the lectures are very clear. And I understand everyrhing.
difficult subjects are explained by simple words by Georgina. Thanks so much!
I recommend everyone to Follow the 100 Day Study Plan given in Lecturio App. Its Amazing.
hi first of all she is talking very will as good speaker and the explanation in different lecture was so systematic and will prepared and hit the main points that I'm really interested to her course of biology.
Great lecture! Very simplified and friendly explained. Thanks so much !
Each RNA should be shown in the picture like above
It is a good course but the content here is not really high yield.Do we need to spend so much time on it?
Very clear and useful for me to finally get a grip on this topic.
i can't understand why a lot of amazing videos have 1star points
Dr. Cornwall makes the topics easy to understand and retain. Her approach is not overwhelming but yet not so simple you are bored.
The lecturer tripping up make it a little difficult to follow but it is made clear in the end.
Talking about things that aren't on the slide https://www.ratemyprofessors.com/ShowRatings.jsp?tid=833581
Very detailed. Moves through information and a good pace. Sifts out the important information versus stuff we don't need to know for the exam.
the concepts are clear and the time is enough, examples are short.
This is incredibly difficult to follow with the lecturer mis-speaking constantly
??? ???? ?? ??? ?? ??? ??? ???? ??? ?? ?? ??? ?? ??? ???
I believe the term is entropy is misused in this lecture.
Most of us studying at this point (USMLE Prep) know this stuff well, however; this does provide a good refresher to get the juices flowing in the right direction while studying for the boards.
Misuse of the words fludity and stability as if they were synonyms makes answering the question at the end confusing. Other than that, it's a good lecture.
Awesome analogy great lecture! Very nice lectures overall I really enjoyed them. even though I have taught this topics and I know them fairly well. I enjoy little gems of information I received through these lectures, and new understanding
This is one of the few videos in this video series where the video cuts before the lecturer is done talking or before she's done with the material for the section. For example, in this one she only discusses E site and video cuts... what about the other 2 sites on the ribosome?
The instructor reading off the podium is not appreciated. It doesn't entice the viewer to keep watching.
I like a lot both the explanations and illustrations to the topic.
I like how Dr. Cornwall recaps chemistry and relation to energy to cells. Her hand motions help with my learning and understanding. Thank you.
Didn't explain clearly and concisely which each type of RNA was as well as providing its clear function. Additionally, it is best to provide the correct definition thus, followed by an analogy. Starting with an analogy of how the different RNA types can make the lesson hard to follow as well as, causing confusion in the actual definition of the term. This particular video was hard to gather information from.
4/5 also add on the replication bubble but as far as the other information well done i understood the concept
I like the practical comparisons used for better understanding and remembering the topic, makes it much easier and more entertaining!
Concise and to the point for basic understandment of the subject.
Thank you dear Ms Cornwall l easily grabbed basic elements and mechanism of cell biology with your videos Best wishes
It was a great lesson thanks for everyting short and briefly everyting.
I really liked the videos they very clear and easy to understand , they best part is they are short and precise to the point .
The marcomolecules lectures are very good with excellent explainations of content
Great lectures, very clear and understandable! Thank you, Dr Georgiana Cornwall!
Great lecture which allowed me to understand the topic much better than I was taught
Explains concept very well with good analogies that further enhances my understanding.
The knowledge is systematic, but I wait for long time to get a answer to my questions. And I still get no feedback.
Dr Cornwall has the gift for teaching!! She explains things very well, thank you!
The module is complete but the questions can get too easy
I really enjoyed the video and it made me learn, also I liked that are short videos
They are so awesomely explained and very helpful thank you. I’d love the videos to have that ten second rewind or fast forward arrows like YouTube does, and then it would be perfect.
she was understandable! i liked her! i am so prepared for the next test we will be doing
Very concise. Great illustrations. Thank you. Thank you. Thank you
The professor did not do a good job explaining concepts clearly, went too fast, covered little material
there wasn't enough details at some points. The topics, for me, are a little tough and the techer wasn't seems to be confident with the material. although the slides are very helpful to understand the topic.
Concise, easy to follow, great drawings, post questions provide a good summary of key points before
amazing lecture, finally i understood the tertiary structure for the first time
Good and informative, no bad comments. Good lectures and lecturer
Good, where are the rest of the organelles (like peroxisome)
Need lot of detailed explanations.. especially in videos. The teacher is really good but the script is lacking too much.
I love this app but can get a little confusing when the professor uses the wrong words or accidentally says the wrong thing. Do you not edit errors out? It’s a great platform just needs a few tweaks here and there.
Easy to understand and fun! Really useful! Great examples are provided!
This is pretty good introduction! haha how to control the cell cycle
I thought that this was very thorough and went over lots of the material that my current professor is going over. Some of the questions were either a little simple but reiterated take home points, or were left-field as the material was not covered in the specific video I just watched. Overall I would recommend this course to anyone struggling in genetics + read the comments because she does a great job in answering and clarifying questions you may not know that you had.
I loved the correlation with margarine and butter, it helps to understand and remember the topic.
I like so much the content of this course and how the doctor provide the information
I found this lecture very concise and easy to despite being quite basic. I have always struggled with understanding atomic structure and feel that it's due to information overload. This lecture provides just the right amount of information to build on.
Concise with good use of slides and professional presence and dress.

I liked it very much because it helped me access materiel that I already new without further complications. It was very easy to comprehend and I will recommend this to everybody needing this for whatever the reasons you need it for.
Appreciate too much, because after many readings in the books, finally I understand clear having the big picture of this topics . Congratulations to the Teacher .
she looked like she was reading from a script and not focused or natural.
Amazing lectures. Simplifies complex pathways and process. Really fantastic! Watched every lessons.
she explains it to the point and doesnt waste time going around the topic.
Well done! Very targeted information. For those that say it’s not as deep as their classroom lecture, it is not designed to be. Again,what we are supposed to get out of this course is the high yield information...and we are getting it. Thank you so much Dr. Cornwall.
Easy to understand...high yield information....great graphics,well done!
Easier to comprehend with the use of great illustrations. concise and crisp presentations
Made it very easy to understand. Thank you very much!
Almost no information really disappointing. Use Step 1 2018 page 46 ... Even a student could have presented the topic in more depth as it is important.
a tough subject, but Dr. Georgina made it very easy and palatable, thanks soo much.
I just want to admit that this tuition is a hard one and she made it very easy.
just excellent , the content and the preparations were realyy excellent and goes very easy.
I believe that she is a great lecturer but, the issue is the way of delivering the lesson and how much was she ready to record the tuition. anyway it was a good experience for both of us, she let me search a lot for the genetics to unwind condense informations :)
Very disorganised way of explaining concepts It would be much better if things were presented in more detail and if the presentations were structured adequately
Concise and clear beginning in cell biology and homeostasis to warm up.
The lecturer did not appear confident looking into notes too often. Too many hand gestures are a distraction especially when not pointing to the stuff on the slides. The material was not presented in an easy or simple way. Made it more complicated that it actually is. I feel difficulty in continuing to the next lectures without understanding this.
I wish all professors prepared students for Biology courses with this explanation. Thank you for addressing this concept!
To the point, clear, precise, great tone and flow. Well planned curriculum.
I feel like she is just reading notes that she has been just handed over.
The presentation is simple, short and concise preparing students for more detailed content. I believe that this is an efficient approach toward a broader base of an audience. Thank you!
the course was good, the first video was condensed with a ton of information and I think you should maybe think about splitting this kind of videos in the future, I was finding myself watching other youtube videos to study this subject. it is always good to use plenty of different source of information to develop a wide perspective on a subject. but in this case, I want to rely on lecturio only.
Dr. Cornwall is very thorough and paces herself very well in relating core concepts.
most of the things i catch from animation while only little from lecture (for which i had to pause the video to read all those stuff written there, which is time consuming). mam's speech seems quite a kind of nervous, suffocating type
5 rating is what you deserve , i really liked the way you illustrate those key aspects
So much more simple than my lectures. Thanks for the detailed lecture. You're a life saver.
"... and we know that the DNA was taken up because the plant grows tumors OR NOT..." Taking the term "tentative scientific language" to another level!! LMFAO >D
In my school we will take this lecture in 2 hours!!! Way too short and superficial
She talks too fast. Also reads too much from her papers. Seems like she's not sure of what she is teaching.
She talks too fast. Additionally, she reads from her notes too much, strikes me as someone who does not have a firm grasp on what she is teaching.
As much as your stories are interesting for the ETC gradient It does not fit my learning style. It would be nice to have clear scientific language about what's happening. I can't write a story on my exam paper. Perhaps this is just me.
Easy to understand and very complete. Thank you for your time, helped me a lot
Feels like she is not comfortable with information she is teaching. Accuracy of information (and spelling!) is sometimes questionable.
Great Explanation !! I wish we would have had you as a teacher. :)
Wow! Muchas gracias por todo el contenido muy bien explicado! Realmente fue muy interesante y, de gran aprendizaje asistir a todos los videos del curso "Introduction to Cell Biology".
great lecture, very simple and clear. I've finally understood bonds!)) thank you!
I am a biochemistry student studying in the UK I found this so useful especially as a foundation in my initial year of study.
I love the visuals, her method of speaking and the transcript at the end
The combo of visual and review aided in maintaining info
This lecture and the one before were very confusing. You need to explain that the third energy level can technically hold UP TO 18 electrons (s,p,d sublevels) but it also fills up with the first 8 it receives. valence shells (energy shells) and energy LEVELS need to be better distinguished and not used interchangeably. Luckily, I knew the material and was able to straighten things out for myself using Google. How can I know that Lecturio will not have faulty lectures in the biochem module (material I'm not familiar with)? I am still within 10 days and am considering cancelling my lecturio subscription over this lost credibility in my mind.
It is very clear to understand. Great job Dr. Cornwall.
Prof Cornwall does a great job at presenting the material, catching my attention easily into the depth of the material while being precise with the content. Very easy to learn from :)
You make it much more easier. However, I still understand all important points. Thank you!
She talks so clear, understandable.. just a little fast but i havent got bored.. Thank you..
I love it so much!!! It’s been a truly rewarding experience for me!
Good lecture, but not USMLE focused. This is more of a general biology lecture than a USMLE prep lecture. It seems to me that Lecturio is not making the difference between MCAT prep and USMLE prep. The lectures look more like MCAT prep lectures and not USMLE.
I like the way she expresses, you can easily understand her
Very good use of examples connecting to every day life.
best prof in the world explains everything so good that even a kid will understand
VERY CLEAR AND EASY TO FOLLOW! IT CAPTURED MY ATTENTION. ALSO LIKED THE FORMAT
Really great explanations of the whole process. Was not happy that I had to relearn Krebs and ETC but actually found these videos enjoyable and valuable.
Great enzyme analogy! Enzyme is the friend who puts his two other friends in contact with each other so that they can start talking and dating ;)
Nothing on how p53 relates to RB or how p53 induces p21 to inhibit CDK thus acting as a tumor suppressor by not allowing cell cycle progression. This info is found in the the First Aid for the USMLE so it is probably important.
I like the smooth flow of the subjects in this course and how they focus on small details that make you digest and understand the living human from very small details.
In terms of studying for something like USMLE, brief intro is fine! Such topics will not be tested on the exam but are necessary to build foundations for other future topics. If you are studying for other exams, this whole module may be a bit light on key information. Great as a refresher though!
There is possibly a mistake in galactosa geometric formula in the lecture
I’m following this course as I’m attending this course at my university, it very helpful, but I wish it was as detailed as our class are.
This is not a USMLE 1 focused topic, an important material for the step, it's so superficial either the question that is a first order question. Need to going deep in the topics, we're not an undergraduate students.
She broke it down to the very basic and helped me get a good foundation
The explanation is very clear, I'm early to continue watching more videos.
Me encanta como se enseña! Ya quisiera tener una profesora como ella en la Universidad!
I had to try so hard to follow what lecture was teaching, subject matter is quite abstract. All the same thanks for trying.
I had to try so hard to follow what lecture was teaching, i remember i enjoyed this better in med sch. All the same thanks for trying.
this topic is quite too cumbersome and lecturer didn't seem to be in control of material presentation
First of all I would like to say that I really appreciate all of the effort by the professors and Lecturio to do great lectures, however, I would like to say, as well, that you need to focus on the exam format (In this case - USMLE Step 1). For example, in this lecture it was asked: "Which of the following is NOT a lysosome related disorder?" that is pretty good, because it has a clinical context with the subject, however this " lysosome related disorder" have never been taught by Professor Cornwall.
The explanations and images are well coordinated, making the review more interesting
The explanations and examples were clear and right to the point
informative. good review for this basic area as it has clinical correlations
Very clear what is going on. I understand it much better.
Loved the lectures, especially the lecture on the electron transport chain. Dr. Cornwall had a really useful analogy of the ETC and kids (electrons and hydrogens) going to the prom (ETC) that really made the concept stick. Very good job!
The chapter about cellular structure has given me clear explanation and enhance my knowledge about the different functions that the plasma membrane assure. The course just makes my understanding of cell dynamic very straightforward.
I feel that the delivery is good but the content is not detailed enough, e.g. when talking about splicing, I think it would have helped to talk about what ‘snurps’ are involved and how this relates to initiation.
It's an excellente teacher! She uses easy analogies that you can memorize quickly and gives you a summary of your class (in my case). Greetings from México!
Excellent structure and content. Essential basics for chem and biol.Thank you.
Well organized backed with excellent methods of teaching & illustration. In summary, I found what I want in short period of time.
Me gusto mucho porque pude repasar el tema sobre la homeostasis.
very good, is complicated, but i understand everything, she is a good teacher
I wish all the other professors had her didactics. Pointing clearly the goals of the presentation before and after the lecture helps us to mentally organize the subject.
I agree that it was brief if someone was looking for something more comprehensive. It was sufficient for me as I only required this to understand one lecture slide however not enough questions.
it is really good ,some hesitation at the beginning but the diagram is very informative ,whopple hypothesis needs more explanation.
The course is informative and up-to-date, which is really important for me. I took my science courses before 2010; now, I’m preparing to take the MCAT. It is an excellent review of content.
Gooood job LoL and really a good story-maker????Thank you very much! Amazing, very impressive!
Thank you very much!! So funny and interesting! I laughed many times LoL also learned A Loooot!!!
I do not think there can be any simpler explanation of these concepts. Dr. Cornwall takes her time to explain these concepts in a way that they stick with you, and the analogies she uses engrave them into the medulla so that you can relate to the concept. You can't beat this! This is exceptional!!!! Thank you so much!!
First step to refresh and understand different concepts. Highly recommended.
excellent she is a very good teacher, the grafhics are didactical she explains in a very simple way, i like it
I like the fact that the lectures are detailed and Dr.Cornwall makes it fun and easy to understand.
The course was well explained. It is confusing subject matter, but she did her best to make it understandable. She is funny, energetic and lively
This is course is still challenging me but i can understand how abstract the concepts are i think i need an in-depth review of course
Thank you Dr. Cornwall, I really think genetics is quite a difficult concept so you are doing your very best, i must admit its very confusing at times i will need go over the concepts again.
I really loved it, because PhD Cornwall made it really easy to understand.
This lecture was excellent in every way, I must say DR. Cornwall is a Pro in intermediate metabolism. I couldn't understand this processes better in medical school than she has made me.
Brilliant. I recommend this course strongly if you want to understand this topic.
Based on explaination. I felt there was some lack of informations. In some area needs to be more profound.
Great lecturer who is knowledgeable about the subject. However the animations in both mitosis and meiosis would have been in motion so the explanations were tuff to follow. overall good attempt. keep up the good job.
great lecturer who is very knowledgeable about the subject matter, pitch, diction and pace is terrific. keep up the good job.

This instructor makes this course enjoyable, and very easy to understand the materials presented here. I have already informed all my friends who are interested about going to medical schools about lecturio. Lecturio is a blessing to mankind.
Excellent lectures, you can understand in a few minutes the basics of difficults topics
Well explained she took her time tho but she did it well
An excellent, brief and up to date piece of information, ideal for quick recall
Well done by the professor with full of transfer sense.
couldnt understand a thing. Please try to use animation to explain better
Classes have an excellent quality, however there are small mistakes when you´re reffering to some specific molecules such as cAMP and cGMP because in some ocasions, you tend to exchange one with the other in just a few ocassions. Nonetheless, the overall course is excellent, with clear explanations.
The explanation is so basic and explicit, hitting all the important fact that, even illiterates would understand. Great lecture!
I am having my genetics exam soon and this course was extremely helpful to better understand the information. Thank you !
u r so good like honestly amazing thank you so much professor
I learned a lot about cell structure in the most simple and efficient way.
It is too much Helping. It is Awesome and helpful
The lecture were short and concise and were just thesame as what I needed to learn.
The lecturer uses great analogies to make concepts easier to understand.
Every topic was clearly explained and I could understand them very well.
These lectures are good , but it needs improvement it should be more in details , and the actions are not mentioned in its orders for example first of all initiation then elongation finally termination ..
I don't waste my time going to any biochemistry lectures at my medical school because I know that Dr Cornwall explains all of the content more clearly, in more depth, in less time. I always finish her lectures excited for the next one!
Brilliant! I have always found these topics extremely confusing at medical school, but Dr Cornwall is able to explain them in such a way that they seem straight forward and easy. This certainly replaces lectures for me! If anybody is unsure about trying this course, they should definitely try it! Dr Cornwall is the best biochemistry lecturer I have seen!
Dr. Cornwall hesitates a lot, and seems unprepared and unsure. Make people feel like she is reading the material and even not familiar with the reading materials. It is really confusing.
Very helpful on understanding the basics of the repair mechanisms.
A great lecture. I am a high school student and i struggle with biology. I get a better explanation from your lectures and I am not even a native English speaker. Thank you so much!
Thank you so much for beautifully explaining every single basic detail in chemistry. The modules covered up the required topics from the scratch to strengthen my basics.
I think this course is really informative, though I would like some more details in subjects like RTKs and G coupled proteins. And also please add English subtitles to this course! I'm not native and I found it hard to keep up!
I liked that she really knows what she is talking about and is able to explain complicated things with examples from everyday life.
Needs more substance. This was barely long enough to be an introduction.
This lecture and the one before are not so well explained. The clamp loader part and the process of semi discontinuous replication need more in depth explanation
it was really helpful,but a bit fast, good details and nice explaining
It helps very much. Thank You. I will share with my friends.
Good clear concept review. Could use more specifics regarding cyclin and cdks.
Structurally complete, however, relatively outdated. Enough for medical study purposes.
Very good keeps on track with my textbook. Taking Intro Bio
great lecture! I still feel the need to fill in the gaps but it has given me an overview of gene regulation
It's very clearly explained and very useful for my studies. I would like it to be a bit more detailed but not too difficult.
Dr Georgina is amazing. Thank you for making all these difficult concepts easier for us.
What I loved the most about this lecture was how Dr. Cornwall actually took her time to explain the concepts discussed, and even used simple analogies to ensure that the information was easier to digest. This is something you find lacking in many professional lectures. Thanks again Dr. Cornwall!
Thank you dr. Georgina Cornwall! Everything was perfectly understood with your lecture!
She spends half an hour explaining the steps of meiosis and doesn't even get into details... I'm not sure how she can manage to explain such simple topics in such a long time (it's half a movie time, for God's sake!). She should base her lectures on Molecular Biology of the Cell, by Bruce Alberts et al., AT A MINIMUM. Lecturio has many excelling lecturers; unfortunately, Dr. Cornwall is not one of them.
Stunning! Explanations are simple and very interesting, wish you all the best professor ????
I like the Lecture it explain many things but there are very important thinks haven't been explained like how to knockout some genes by using shRNA or siRNA. I know that you explain CRSPR which is the greatest method ever . But I think is necessary to talk about shRNA, siRNA and what the advantage and disadvantag because everyday in school we here about them and I think they need to coverd in this lecture. Thanks
Don't replace her. Good OVERVIEW/REVIEW of the material at hand. Her pace is good. Her voice and expression and everything else is dynamic and engaging.
Please replace her. Explanation is very poor, she hesitate a lot, and seems unprepared and unsure. It is confusing and in comparison to a lot of lecturers you have here, the standard is incredibly low!
Great breakdown of these biologically important macromolecules. Amazing detail on presenting each macromolecule and distinguishing polymers, monomers and non polymers.
She is very detailed but yet not overwhelming with the lecture. It's been great help on my bio knowledge.
Not very hard to understand, sometimes a bit too "shallow". However most often very good. Even great.
The professor was very knowledgeable and presented the information in a clear and concise manner
The Dr Georgina did it very well she know detail about the subject matter andinet did not express about her and execelentroll model for me!
Very good explanation and notes and diagrams. Dr has good quality teaching .
I like the way the instructor presents the material , and the examples she uses.
The lecture covered everything I needed to know for my upcoming test. I feel so much more prepared now!
Dr. Cornwall is a good teacher. However the topics move quickly. This is great for biology majors needing a refresher. But for me it is helpful to take a second to restate an important concept or give context on what this process will impact in the future lessons. Helps the listener to remember it when you give it some context.
Well, I love the way Dr. G explains, however, the lecture on cell control wasn't the best and needed more explanations and needed to be more simplified . I put five stars because Dr. G has helped me a lot and made Biology a fun course.
This course really helped me understand the cellular structure, I learnt more from one of the 20 minute lectures, than I did in a 3 hour lecture at university, so these really help!
Good and clear explanation, Dr. G makes it fun to learn biology.
Some parts that the instructor was going through were not gone into depth when they should have and some parts should have their own video.
Just an introductory lecture on any course enkindles a burning zeal to learn more. It is a perfect review lecture on the go and a better way to have fun while learning. A perfect definition of concise learning in a limited period.
I like it a lot. Good review. The slides for mitosis is the wrong one, ie different lecture notes
Impressed by the knowledge of the presenter. However, had a feeling that she was asked to push/rush through some of the concepts in minimum possible hrs. Seems like some concepts needed more time to explain. Overall, I loved this series.
This is fun. I wish they were an accredited school. But they are good for prep.
