Molecular and Cell Biology

by Georgina Cornwall, PhD

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.

It is too simple like introductory biology. We need more advanced molecular biology

Didn't expect this.
By Talwinder M. on 15. September 2022 for Telophase and Cytokinesis – Mitosis

lack of information no explanation ,its like you are reading headings. and the quiz questions are poorly made.

Easy to understand
By Dante A. on 22. August 2022 for Ribosome

Great way to remember the three portions of the ribosome!

Now, I know molecular biology as well as any medical student ought to! :)

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! :)
