    Barbara McClintock worked on genetics in corn (maize) plants and spent most of her life conducting research at the Cold Spring Harbor Laboratory in Laurel Hollow, New York. McClintock's research focused on reproduction and mutations in maize, and described the phenomenon of genetic crossover in chromosomes. Through her maize mutation experiments, McClintock observed transposons, or mobile elements of genes within the chromosome, which jump around the genome. McClintock received the Nobel Prize for Physiology or Medicine in for her research on chromosome transposition. McClintock's work helped explain the behavior of chromosomes in organismal development and identified transposition as a cause of genetic variation.

    Barbara McClintock (born Eleanor McClintock) was the third of four children of Sara Handy McClintock and physician Thomas Henry McClintock in Hartford, Connecticut, born on 16 June McClintock's parents soon changed her birth name, Eleanor, to what they thought to be a fransk artikel
