(A) The correct answer is $A$. In $1941$,George Beadle and Edward Tatum proposed the one gene-one enzyme hypothesis. This hypothesis states that each gene is responsible for the synthesis of a specific enzyme that controls a particular metabolic step in an organism. This work laid the foundation for biochemical genetics,for which they were awarded the Nobel Prize in $1958$. Later,this theory was refined to the one gene-one polypeptide hypothesis,as many enzymes are composed of multiple polypeptide chains,and one gene typically codes for one polypeptide.
