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 experiments led them to propose a direct link between genes and enzymatic reactions, known as the One gene-one enzyme hypothesis.
After retiring, Beadle undertook a remarkable experiment in maize genetics.
