In a prokaryotic operon, the promoter functions to bind the RNA polymerase. bind the repressor. break down lactose. prevent the expression of lac genes.
Dominador T.
The lac operon genes only become expressed if: lactose binds to the repressor glucose binds to the repressor lactose binds to the operator the repressor binds to the operator
Joanna Q.
With regard to the lac operon, which of the following is false under conditions of low (or no) glucose? Answer: RNA polymerase can bind to the promoter. Answers: Lactose anabolism will occur. The repressor is not bound to the operator. Allolactose is bound to the repressor. RNA polymerase can bind to the promoter.
