WebBy February 1941, Tatum and Beadle began exposing Neurospora to X-ray in order to obtain mutants that would have biochemical defects because of nutritional deficiency. Ultimately, it was the mutant number 299, which was the first identifiable mutant that required pyridoxine for normal synthesis. WebApr 18, 2005 · George Beadle was a towering scientific figure whose work from the 1930s to 1960 marked the transition from classical genetics to the molecular era. Among other distinctions, he made the pivotal, Nobel Prize-winning discovery with Edward Tatum that the role of genes is to specify proteins.
