A regularity gene produces some kind of protein through its m-RNA that controls the activity of the operator gene which signals the formation of specific enzyme required for the metabolic breakdown of the food. How does that protein regulate the activity of the operator gene?

Options

A. The mutated repressor protein produces activates the operator gene
B. The catabolic activator protein (CAP) produces activates the operator gene
C. The repressor protein produced, after combining with an inducer leads to activation of the operator gene
D. The mutated repressor protein produced activates the operator gene

Answer

D
