BIOL 123: Introduction To Comparative Virology

Explore the fascinating intersection of human and prokaryotic genetics revealing that both contain about 1000 shared genes despite their complexity difference. The video explains how this common genetic heritage can be traced back to a universal ancestor covering the essential functions these genes perform like metabolism and DNA replication.

Learn about mouse genetics and the implications of dominant and recessive genes on coat color. We'll use a Punnett square to predict offspring coat patterns by crossing two heterozygous mice. Learn how phenotype ratios like 9 Agouti: 4 white: 3 black help us understand genetic outcomes.

Discover the intricate details of the pelvis anatomy as we analyze and correct misconceptions about its structure and components, using sketches for clarity.

Dive into the biochemistry of haemoglobin, a pivotal protein in red blood cells. We assess key statements about its structure and function, clarifying common misconceptions.

Primary succession is the process of converting barren, lifeless rock into a flourishing terrestrial community. This ecological transformation begins with pioneering species and lays the foundation for complex ecosystems.

Discover the fundamentals of the respiratory system and the primary muscle behind inspiration. This video breaks down the physiological process of breathing, the key role of the diaphragm, and why other muscles don't initiate breathing.
