Summary: Free radicals are an important weapon in the immune system, but they can also cause chemical reactions that lead to damage of fatty acids, DNA mutation, and protein destruction. This program examines how the most important radicals are created, and how they work. The relationship between chain reactions of radicals within the body and conditions such as arteriosclerosis is examined. How the...

Summary: Proteins, the essential biochemical foundation of the cell, fulfill a variety of tasks within the human body. This program provides insights into their structure and several of their functions, including their role in catalytic biochemical reaction and reproduction. How proteins recognize the "packaging" of smaller molecules is explored. Using a photosynthetic protein-a proton pump-as an...

Summary: Viruses are the simplest forms of life-so primitive in biological terms that for some years the scientific community debated whether they should even be regarded as living organisms. This program examines how viruses, though incapable of reproducing outside of living cells, have developed refined strategies for reconfiguring the host organism into one that serves exclusively as a virus breeder....

Summary: This program presents the human body as a complex ecosystem of bacteria, then examines each portion of the body, which bacteria live there, and why. The three major bacterial groups-sphere-shaped cocci, rods, and helical spirochetes and spirilla-are examined. Their behavior when interacting within the body is explored. The life and death of obligate aerobes, facultative anaerobes, and obligate...

Summary: This program shows the various types of gene reproduction and examines the gene responsible for blood clotting. The production of coded proteins is clearly demonstrated. The processes of gel filtration, protein sequence analysis, isolation of mRNA, DNA synthesis and reproduction, production and screening of a DNA bank, and hybridization, along with other demonstrations, are re-created through...
