If lactose and glucose are provided in the growth medium of a culture

1.	If lactose and glucose are provided in the growth medium of a culture of E. coli ____________(a) Lactose operon is not transcribed(b) Lactose metabolism is favored(c) Both lactose and glucose are metabolized at same rate(d) Adenylate cyclase is activatedI have been asked this question in a national level competition.This interesting question is from Principles of Gene Regulation topic in division Regulation of Gene Expression and Miscellaneous of Biochemistry
Answer» CORRECT choice is (a) Lactose operon is not TRANSCRIBED To explain I would SAY: If lactose and GLUCOSE are provided in the growth medium of a culture of E. coli lactose operon is not transcribed.
