Video 32: Nathaniel Comfort, clip 3
Nathaniel Comfort published The Tangled Field (2001), a biographical study of McClintock's life, thought, and impact. In this clip, he notes that Barbara McClintock identified the correct haploid number of chromosomes in maize (10) and connected genetic linkage groups with specific areas of chromosomes. She observed distinct knobs and bands at late prophase.
