Scientist Dr. Barbara McClintock had a long career during which she made several important breakthroughs and earned distinguished awards for studying the genomics of maize (corn). In 1983, at the age of 81, McClintock was awarded the Nobel Prize in Physiology or Medicine for her work on so-called "jumping genes," or genes that change position on the chromosome. The newest addition to the National Library of Medicine's Profiles in Science online series (last discussed in the May 18, 2001 Scout Report
) is an exhibit of the Barbara McClintock Papers. This site is divided into sections that focus on Dr. McClintock's life and major scientific contributions. Each section provides text or images of original materials such as laboratory notes, correspondence, journal articles, unpublished manuscripts, grant proposals, lecture notes, photographs, and illustrations (.pdf). Students of genetics and anyone interested in the history of science should browse this online exhibit.
