Twenty years after the discovery of DNA’s structure, another revolution swept biology when scientists began learning how to manipulate genes outright. The controversy continues. This program tells the story of genetic engineering’s pioneers, focusing on the race to synthesize insulin and the development of genetically modified crops. Spectacular computer animations of molecular processes are paired with extensive commentary by key researchers, including Genentech founder Herb Boyer, Stanford University biochemists Stan Cohen and Paul Berg, former Genentech scientist Dave Goeddel, Nobel Laureate Jim Watson, Harvard University molecular biologist Walter Gilbert, and Monsanto biochemist Bob Horsch.
