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. The student will acquire an introductory understanding of chemistry, with special emphasis on the properties of the carbon atom, as well as of physics, focusing on the principles of thermodynamics and electricity.

cell signaling and recetrors, also I understand well the juctions in the cell membrane
By JOHN M. on 23. January 2022 for Cellular Structure

Simplified and we'll explained. The teacher knows her topics well and explains in a simple way for all to understand.

very clear , and natural. High yield, very in depth. Great knowledge gained

I get it NOW!
By Chris L. on 26. December 2021 for Language of Chromosomes – Mitosis

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.
