The lac operon consists of regulatory regions such as the promoter as well as the structural genes lacZ, lacY, and lacA, which code for proteins involved in lactose metabolism. What would be the outcome of a mutation in one of the structural genes of the lac operon? a. Mutation in structural genes will stop transcription. b. Mutated lacY will produce an abnormal βgalactosidase protein. c. Mutated lacA will produce a protein that will transfer an acetyl group to βgalactosidase. d. Transcription w
