Barbara McClintock Hall, located on the campus of Cornell University in Ithaca, New York, is a prominent building named after the renowned American geneticist Barbara McClintock. The hall serves as a testament to McClintock's groundbreaking contributions to the field of genetics and her legacy as a pioneering female scientist. McClintock's work on the transposition of genetic elements in maize (corn) led to the discovery of transposons, which are mobile genetic elements that can jump from one location to another within a genome.
Biography of Barbara McClintock
Barbara McClintock was born on June 16, 1902, in Hartford, Connecticut, to Thomas Henry McClintock and Sara Handy McClintock. She developed an interest in science at an early age and pursued her undergraduate degree in botany at Cornell University, where she graduated in 1923. McClintock then went on to earn her master’s degree in botany and genetics from Cornell in 1925 and her Ph.D. in botany and genetics in 1927. Her doctoral research focused on the cytology and genetics of maize, which laid the foundation for her future discoveries.
Career and Achievements
McClintock’s career spanned over five decades, during which she made significant contributions to the field of genetics. Her work on the transposition of genetic elements in maize led to the discovery of transposons, which are now recognized as a fundamental component of many genomes. McClintock’s research also shed light on the mechanisms of gene regulation and the role of transposons in shaping genome evolution. In 1983, she was awarded the Nobel Prize in Physiology or Medicine for her discovery of transposons, becoming the first American woman to receive an unshared Nobel Prize in that category.
