No biological sciences have more promise for the future of mankind than genetics and microbiology. Microbiology, which includes genetics, is the story of understanding how the cell works: All life is cellular life; all animal and plant tissue is made up of cells; all infectious diseases are caused by invading cells; cell division is the process of creating all complex life; and all genetic material is contained within the cell. Segments include: Mendel's Laws of Inheritance; Germ Theory of Disease; Structure of Cells; Mitosis and Cell Division; Meiosis; the Symbiotic Cell. Spanish subtitles.
