The Structure, Growth, Physiology, and Genetics of Prokaryotes and Viruses

The Structure, Growth, Physiology, and Genetics of Prokaryotes and Viruses

by Vincent Racaniello, PhD, Sean Elliott, MD

This course covers the material of content category 2B of the official MCAT exam content outline.

Bacteria are single-celled prokaryotic organisms, believed to be the most ancient living organisms on Earthโ€”so much so that mitochondria and chloroplasts likely evolved from bacteria that were engulfed by proto-eukaryotic cells. Viruses, just as ancient as bacteria, are microorganisms constituted by sequences of genetic material encased in a protein capsule, which hijack the cellular machinery of eukaryotes to multiply themselves. Today, humans have a complex relationship with both of these organisms. While some are normal colonizers of body surfaces and tracts, others have pathogenic potential and can, therefore, be harmful.

In this course, the discussion will center around the basic concepts of bacterial and viral physiology. For optimal comprehension, the student will be required to have preliminary, college-grade knowledge of molecular and cellular biology and biochemistry.
