Amutant strain of e. coli produces β-galactosidase in the presence and in the absence of lactose. where in the operon might the mutation in this strain occur and why? a-in the operator region, where the mutation leads to the failure of the operator to normally bind the repressor b-in the cap binding site, where the mutation leads to the inefficiency of rna polymerase activity c-in the promoter region of the operon, where the mutation leads to the failure of the rna polymerase to bind to the promoter d-near the laci gene, where the mutation leads to increased levels of lac repressor being made e-in the laci gene, which leads to an inactive lac repressor f-in the operator region, which leads to increased binding of the lac repressor to the operator
