The Secret of Genes [electronic resource]

Longevity may or may not come from one's family tree-but with the help of science, could it one day be "inserted" into our genes? This program looks at research in genetic modification that might help extend human life spans. Spotlighting recent DNA experiments on the C. elegans worm, the program also describes longevity studies in mice, mollusks, and fungi-all of which shed light on possibilities for genetic alteration in humans. Students will learn about the roles played by mitochondria and free radicals while the genetic implications of diet and metabolism are also explored. Conclusions based on studies of Okinawan populations and the Biosphere 2 venture of the early 1990s are featured.
