George Beadle

George Beadle was a prominent American geneticist known for his groundbreaking work in understanding genes and their role in heredity. He, along with Edward Tatum, proposed the "one gene, one enzyme" hypothesis, suggesting that each gene in an organism's DNA is responsible for producing a specific enzyme that controls a particular step in a biological process. This idea significantly advanced our understanding of genetics and biochemistry, paving the way for modern molecular biology. For his contributions, Beadle was awarded the Nobel Prize in Physiology or Medicine in 1958, influencing research on genes, DNA, and the fundamentals of life itself.
