Barbara McClintock, (born June 16, 1902, Hartford, Connecticut, U.S.—died September 2, 1992, Huntington, New York), American scientist whose discovery in the 1940s and ’50s of mobile genetic elements, or “jumping genes,” won her the Nobel Prize for Physiology or Medicine in 1983.
Where did Barbara McClintock discovered jumping genes?
maize
In the late 1940s, Barbara McClintock challenged existing concepts of what genes were capable of when she discovered that some genes could be mobile. Her studies of chromosome breakage in maize led her to discover a chromosome-breaking locus that could change its position within a chromosome.

What are 2 facts about Barbara McClintock?
At the age of 81 in 1983, she became the first woman to win a solo Nobel Prize in Physiology or Medicine for discovering genetic transposition, when genes change positions on chromosomes. She used the concept to explain how genes can cause certain physical characteristics to be turned on or off.
What did Barbara McClintock discover in 1950?
During the 1940s and 1950s, McClintock discovered transposition and used it to demonstrate that genes are responsible for turning physical characteristics on and off. She developed theories to explain the suppression and expression of genetic information from one generation of maize plants to the next.
Who gave the name of chromosome?
Wilhelm von Waldeyer-Hartz
The word chromosome was originally coined in German from the Greek words khroma, meaning “color,” and soma meaning “body.” In the late 1800s, a scientist, Wilhelm von Waldeyer-Hartz, gave chromosomes their name because chromosomes easily accept dye and take on patterns of light and dark when exposed to different stains …
