Barbara McClintock
Barbara McClintock (June 16, 1902 – September 2, 1992) was an American geneticist who became one of the most distinguished figures in the field of genetics. She is best known for her discovery of transposable elements, or "jumping genes," a finding which has had a profound impact on genetic research.
Early Life and Education[edit | edit source]
McClintock was born in Hartford, Connecticut, in 1902. She developed an interest in science at a young age and pursued her passion at the Cornell University College of Agriculture, where she earned her bachelor's degree in botany in 1923. She continued her studies at Cornell, earning a master's degree in 1925 and a Ph.D. in botany in 1927.
Career and Research[edit | edit source]
After completing her education, McClintock accepted a position at the University of Missouri, where she began her groundbreaking research into the genetics of maize. It was during this time that she discovered transposable elements, or "jumping genes," which are segments of DNA that can move from one location in the genome to another. This discovery challenged the prevailing view of genetics at the time and has since become a fundamental concept in the field.
In 1941, McClintock was elected to the National Academy of Sciences, becoming the third woman to achieve this honor. She continued her research at the Cold Spring Harbor Laboratory in New York, where she remained until her retirement.
Legacy and Honors[edit | edit source]
McClintock's work has been widely recognized for its significance and impact. In 1983, she was awarded the Nobel Prize in Physiology or Medicine for her discovery of transposable elements, becoming the first woman to receive the prize unshared. Her other honors include the National Medal of Science and the Albert Lasker Award for Basic Medical Research.
