Early in his professional life, George Wells Beadle worked in the laboratory of Thomas Hunt Morgan, the geneticist who helped to revolutionize what we know about genetics--the inheritance of characteristics by the deoxyribonucleic acid (DNA) found in...

George W. Beadle's innovative and diverse research with corn, fruit flies, and bread mold helped to demystify the activities of genes, making it possible to reduce the inheritance of a particular characteristic to a series of steps needed for the...

The American scientist, educator, and administrator George Wells Beadle (1903-1989) demonstrated the role of genes in the control of biochemical reactions in living organisms. George Beadle was born on October 22, 1903, in Wahoo, Nebraska. He obtained...

1903-1989 American Geneticist In 1958 George Wells Beadle shared the Nobel Prize in medicine with Joshua Lederberg (1925- ) and Edward Lawrie Tatum (1909-1975) for their discoveries that demonstrated the relationship between genes and the proteins they...

1903-1989 American biologist who shared the Nobel Prize in physiology or medicine with Edward Tatum for the research that established the "one gene one enzyme" theory. Beadle and Tatum irradiated the common bread mold, Neurospora, and...

Beadle and Tatum's key experiments involved exposing the bread mold Neurospora crassa to x-rays, causing mutations. In a series of experiments, they showed that these mutations caused changes in specific enzymes involved in metabolic pathways. These...
