Barbara McClintock made significant discoveries in genetics, particularly through her work on maize (corn). She identified "jumping genes" or transposable elements, which can move within and between chromosomes, challenging the fixed nature of genetic sequences. Her pioneering research revealed how these elements can influence genetic expression and contribute to genetic diversity. McClintock's work earned her the Nobel Prize in Physiology or Medicine in 1983, highlighting her contributions to our understanding of genetic regulation.
