Vedclass · Answer

(D) The 'one gene one enzyme' hypothesis was proposed by George Beadle and Edward Tatum in $1941$. They conducted experiments on the bread mold $Neurospora crassa$ to demonstrate that genes act by regulating definite chemical events. They observed that specific mutations in genes resulted in the loss of specific enzymes, leading to the conclusion that each gene is responsible for the synthesis of a single enzyme.
