Biographical Overview | Barbara McClintock - Profiles in Science
I could just work with the greatest of pleasure. I never felt the need nor the desire to defend my views. If I turned out to be wrong, I just forgot that I ever held such a view. It didn't matter. Barbara McClintock was born June 16,in Hartford, Connecticut, one of four children of Thomas Henry McClintock and Sara Handy McClintock.
Her family moved to Brooklyn, New York, in She graduated from Erasmus Hall High School in McClintock earned her B. and M.
degrees in botany at Cornell University, and received her Ph. in the same subject at Cornell in Although women were not permitted to major in genetics at Cornell, she became a highly influential member of a small group who studied maize corn cytogenetics, the genetic study of maize at the cellular level. In the early s, prestigious postdoctoral fellowships from the National Research Council, the Guggenheim Foundation, and others, enabled Dr. McClintock to pursue genetics research at several different institutions, including Cornell, the University of Missouri, and the California Institute of Technology.
Part of this postdoctoral training included six months in Germany inbut mounting political tensions across Europe forced her to return to the United States earlier than she expected.
McClintock returned to Cornell for renaissance research papers more years until, inshe accepted a position as an assistant professor at the University of Missouri at Columbia from renaissance research papers influential maize geneticist Lewis Stadler.
Byhowever, she believed that she would not gain tenure at Missouri, and left her job. In Decembershe was offered a one-year research position at the Carnegie Institution of Washington's Department of Genetics at Cold Spring Harbor on Long Island, New York.
This job turned into a full-time staff position the following year. Inafter 26 years of committed research, McClintock retired from the Carnegie Institution, which awarded her a Distinguished Service Award. She was invited to stay at the Cold Renaissance research papers Harbor Laboratory as a research scientist. She remained affiliated with the laboratory until her death in Throughout her long and distinguished career, McClintock's work focused on the genetics of maize and, renaissance research papers, in particular, the relationship between plant reproduction and subsequent mutation.
Beginning in the late s, she studied how genes in chromosomes could "move" during the breeding of maize plants. She did groundbreaking research on this phenomenon, where she determined the physical correlate of genetic crossing-over. Later, during the s and s, McClintock showed how certain genes were responsible for turning on or off physical characteristics, such as the color of renaissance research papers or renaissance research papers corn kernels.
She developed theories to explain the suppression or expression of genetic information from one generation of maize plants to the next that defied the common wisdom of molecular biology prevalent during the s. After encountering some skepticism about her research and its implications, she refrained from publishing her data in professional journals and only shared her research with a small circle of loyal colleagues. InMcClintock received funding from the National Science Foundation and the Rockefeller Foundation to study different varieties, renaissance research papers, or races, of maize in South and Central America.
In the early s, renaissance research papers, she traveled extensively, renaissance research papers, collected maize samples that demonstrated interesting evolutionary characteristics, and mentored junior scientists and young graduate students renaissance research papers maize genetics. McClintock and her colleagues spent two decades assembling data on differences in South American maize, which were finally published in as The Chromosomal Constitution of Races of Maize.
McClintock was recognized throughout her career as one of the most distinguished scientists of the renaissance research papers century.
Inshe became the third woman elected to the National Academy of Sciences. She was the first woman to become president of the Genetics Society of America, to which she was elected in InPresident Richard M. Nixon awarded McClintock the National Medal of Science. InMcClintock became the first recipient of a MacArthur Foundation Grant, now known informally as the "genius" grant, which was awarded for her lifetime.
In that same year, she was given the Albert and Mary Lasker Award. Inat the age of 81, renaissance research papers, she received the Nobel Prize in Physiology or Medicine for her work on "mobile genetic elements," that is, genetic transposition, or the ability of genes to change position on the chromosome. McClintock was the first woman to receive an unshared Nobel Prize in that category. McClintock died at Huntington Hospital, near Cold Spring Harbor, on September 2,at the age of Toggle navigation Barbara McClintock - Profiles in Science.
