Start NowThis course covers the material of content category 1B of the official MCAT exam content outline.
Traits associated with survival are codified and passed down from generation to generation via genetic material. In order for traits to be materialized, they must be decoded and translated into proteins via gene transcription and translation. This is known as the central dogma of biology, the mechanism of inheritance and expression of evolutionary advantages that has ensured the preservation of all species currently living on the planet, including human beings.
In this course, the student will be introduced to the processes of transcription and translation of genetic information in eukaryotes and prokaryotes. For optimal comprehension, the student will be required to be familiar with the basic concepts of college-grade biology and chemistry.

The analogy of the central dogma is the best explanation I've ever heard!!
I appreciate the approach to clear concepts and road map to the subject matter.
Topic is not comparing the topics from previous topics in the table form. Then students will remembered
Ms Cornwall presentations hard to understand with no clear imaging and orientation of the slides

It is too simple like introductory biology. We need more advanced molecular biology
Great way to remember the three portions of the ribosome!
Georgia Cornwall has done a conscientious job at teaching molecular and cellular biology -- and I enjoy it daily! :)
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.
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.
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.
very good knowledge gained. Learnt a lot about RNA and DNA and messenger RNA
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.
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.
A student could do this lecture and it would be easier to understand. we expect better lectures from professors.
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.
Beautiful and very good explanation . easy slides. thankyou. study matter also provided
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.
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.
Very condensed, but a well-taught lecture. I love the teacher´s style.
SHE IS NOT CONFIDENT IN TEACHING AND RUINS THE MOOD OF LEARNING
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
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.
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
Despite the mishaps, I thought the information was understandable. Especially the ending when she connected Trp and Lac operons with repressible and inducible.
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
Good explanation. Pretty bad diagram. Animation probably would work better.
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.
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.
the explanation is complicated it could be simplified more better
Each RNA should be shown in the picture like above
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
This is incredibly difficult to follow with the lecturer mis-speaking constantly
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.
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.
she was understandable! i liked her! i am so prepared for the next test we will be doing
The professor did not do a good job explaining concepts clearly, went too fast, covered little material
Explains it completely from the start to the end , everything is clear and simple . The structure is very easy to understand.
I really liked this site ,and it's seems helpful for me . I am a high school student. I am in the 10th grade right now. I just want to become a surgeon doctor because I want to save peoples lives. I know that I have to right a commit to this site and I do not have to introduce myself for you people. I do not need to study this because I did not understand today's subject.I just want to be ready for the medical school. I hope this website will help me being ready and ,Good Luck.
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!
"... 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
Conveyed the process in a short &digestable way.I LIKED THE WAY OF presentation too.
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.
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.
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 is really good ,some hesitation at the beginning but the diagram is very informative ,whopple hypothesis needs more explanation.
excellent she is a very good teacher, the grafhics are didactical she explains in a very simple way, i like it
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
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 am having my genetics exam soon and this course was extremely helpful to better understand the information. Thank you !
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.
Structurally complete, however, relatively outdated. Enough for medical study purposes.
great lecture! I still feel the need to fill in the gaps but it has given me an overview of gene regulation
Dr Georgina is amazing. Thank you for making all these difficult concepts easier for us.
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!
