Video 32: Nathaniel Comfort, clip 5

Nathaniel Comfort published The Tangled Field (2001), a biographical study of McClintock's life, thought, and impact. In this clip he says that once McClintock discovered that AC and DS could transpose (move from place to place), she could explain how they could regulate the actions of other genes, thus linking development and heredity in maize.
