Date 19 Which of the following is true with respect to the lac operon a The repressor only binds to the operator when it is bound to the product of the enzymes coded for by the genes of the operon b The repressor only binds to the operator when it is bound to the mRNA transcript of the lacZ and lacy genes c The repressor only leaves the operator when it is bound to the protein product of the lacl gene d The repressor is always bound to the operator but changes shape when lactose binds to it allowing RNA polymerase to pass e The repressor is bound to the operator except when it is bound to the inducer 20 The repressor protein of the lac operon has two different recognition and binding sites for other molecules Which of the following pairs of molecules do you think it likely that these sites would bind a RNA polymerase and lactose b RNA polymerase and DNA c a DNA sequence on the operator and lactose d a DNA sequence on the regulator gene and lactose e lactose and DNA polymerase
