Question

Who proposed that genes control the production of enzymes?

Answer 1

Explanation:

When Spiegelman transferred to Washington University in 1942, he chose as his doctoral thesis topic an obscure phenomenon then known as enzymatic adaptation, subsequently renamed enzyme induction. It was known that the ability of a given microorganism (e.g., yeast) to manufacture various enzymes--the special proteins that catalyze the thousands of chemical reactions in living systems--could be used to track genetic changes in these microbes.
