Let’s suppоse yоu hаve isоlаted two mutаnt strains (called strain A and strain B) of E. coli in which the lac operon is not regulated properly. In both strains, the lac operon is constitutively expressed in the absence of lactose (and glucose). To understand the nature of this defect, you create a merozygote in which each mutant strain contains an F’ factor with a normal lac operon and a normal lacI gene. You then compare each mutant strain and the merozygote with regard to their β-galactosidase activities in the presence and absence of lactose. (Note: glucose was not present in either case.) You obtain the following results: Strain Addition of lactose Amount (%) β-Galactosidase Normal (wild-type) No
