  1. You're on the wrong forum.


  2. Barbara McClintock was a pioneering American scientist and one of the world's most distinguished cytogeneticists.,  was recognized amongst the best in the field,  and elected a member of the National Academy of Sciences in 1944.Her experiments  help to lay the foundation for modern genetics. Almost four decades after her most famous discovery, nicknamed "jumping genes," eighty-one-year-old Barbara McClintock became the first woman ever to receive an unshared Nobel Prize for Physiology or Medicine Barbara McClintock showed that genes could transpose within chromosomes; that they could move around (the so-called "jumping genes") Her work with genetics came only twenty-one years after the rediscovery of Mendel's principles of heredity, at a time when acceptance of those general principles was not wide-spread. Thus her work, which to some now seems to have been ignored when it first appeared, was simply too advanced for many to comprehend at the time.She also traced the evolutionary history of domesticated maize to determine the genetic ancestor of the grass we now call corn.

    Her Nobel lecture was entitled "The Significance of Responses of the Genome to Challenge." In the conclusion to her lecture, referring back to those subjects she had spoken about, she stated "The examples chosen illustrate the importance of stress in instigating genome modification by mobilizing available cell mechanisms that can restructure genomes, and in quite different ways. A few illustrations from nature are included because they support the conclusion that stress, and the genome's reaction to it, may underlie many species formations. She was speaking on no less than a mechanism whereby evolution may occur."
