Barbara McClintock
Barbara McClintock did not have any children. She was a pioneering geneticist known for her work on transposable genetic elements in maize.
Barbara McClintock was a white American scientist of European descent. She made significant contributions to the field of genetics, winning the Nobel Prize in Physiology or Medicine in 1983 for her work on transposons in maize.
Barbara McClintock won the Nobel Prize in Physiology or Medicine in 1983 for her discovery of mobile genetic elements or "jumping genes" in maize.
She was the first person to genetically map maize, or corn. See the related link for more information.
Transposition- "jumping genes" genes that move around almost randomly through the genome in maize or corn
McClintock pioneered the field of maize cytogenetics, or the cellular analysis of genetic phenomena in corn, which for the first time provided a visual connection between certain inheritable traits and their physical basis in the chromosome.

During the 1940s and 1950s, McClintock discovered transposition and used it to show how genes are responsible for turning physical characteristics on or off. She developed theories to explain the repression or expression of genetic information from one generation of maize plants to the next. Hope this helps. Sources: Wikipedia
She studied genetics and came up with the theory of transposition or "jumping genes" which is when a segment of DNA moves from one place to another with the help of chromosones. Hope i helped :)
