George Beadle and Edward Tatum at Stanford experimented with a bread mold (Neuropora crassa). They induced genetic mutations using x rays that affected enzymes involved in making amino acids. Their experiments showed that genes are directly linked to enzyme production. Their landmark explanation that each gene controls the production of a single enzyme, which in turn regulates a specific step in a metabolic pathway, is known as the _____________________________________ hypothesis.
