McClintock was a scientist and one of the world's most distinguished geneticists. She won the 1983 Nobel Prize in Physiology or Medicine, as stated by the Hartford Courant. McClintock earned her doctoral in botany from Cornell University, where she was a leader in the development of maize cytogenetics. The field remained the focus of her research for the rest of her career. McClintock's studies of genetic mutation in maize led to her discovery of "mobile genetic elements," genes that move from one chromosome to another. Although this idea has since formed the basis of modern genetic engineering, it took many years for her discoveries to be accepted.
