Sep 2, 1992 · Barbara McClintock was a Nobel prize-winning plant geneticist, whose multiple discoveries in maize have changed our understanding of genetics. Born in Connecticut in 1902, McClintock began...
Throughout her long and distinguished career, McClintock's work focused on the genetics of maize and, in particular, the relationship between plant reproduction and subsequent mutation. Beginning in the late 1920s, she studied how genes in chromosomes could "move" during the breeding of maize plants.
Dec 11, 2012 · In the late 1940s, Barbara McClintock challenged existing concepts of what genes were capable of when she discovered that some genes could be mobile. Her studies of chromosome breakage in maize led her to discover a chromosome-breaking locus that could change its position within a chromosome.
