Barbara McClintock Facts
Barbara McClintock (June 16, 1902 to September 2, 1992) was the foremost cytogeneticist in the world, best known for her research and resulting theories on "jumping genes."
Interesting Barbara McClintock Facts:
McClintock was born in Hartford, Connecticut, and attended school at Erasmus Hall High School.
She was naturally adept at science and wanted to attend Cornell University to pursue a degree in science, but her mother felt that a girl with such an education would have trouble finding a suitable husband.
Only a short time before registration, McClintock's physician father intervened and she was allowed to attend.
She received a bachelor's degree in botany in 1923, but her interest in genetics was established when she took a course as part of the degree program.
At the invitation of her genetics professor , C B Hutchison, McClintock pursued both a Master's and PhD; despite rumors that women were not allowed to earn graduate degrees in genetics from Cornell-hence McClintock's graduate and post-graduate degrees in botany-those rumors appear to have been false.
During her research and teaching at Cornell, McClintock organized a group of research who would be vital to the study of genetics in corn.
She focused on ways to understand and visual the genetic makeup of the plant for breeding and resistance purposes.
One of these methods involved studying the microspore of the plant as opposed to the root tip, which many researchers had focused on.
McClintock later became the first scientist to understand and diagram the cross-shaped nature of chromosomes during meiosis, which led to later research proving chromosomal crossover.
Among her other continued and vital work, McClintock conducted research into the mutating properties of Xrays and created the first ever genetic map of corn's makeup.
She also was the first scientist to fully understand and outline the centromere and its role in genetics.
Despite her many important contributions, her numerous honorary degrees and fellowships, and her renown as a cytogenetecist, McClintock often faced sexual discrimination at different universities and faced the frustration of not being recognized for her contributions.
