Which of the following could alter the specificity of binding of a repressor with an operator?

Question

Quizplus · Accepted Answer

All three options listed in E could alter the sequence of the operator, potentially changing the specific binding of the repressor. A nucleotide deletion or addition could change the sequence of the operator and disrupt the binding site for the repressor, while site-directed mutagenesis could introduce a mutation that affects the binding specificity. Therefore, all three options in E could alter the specificity of binding between the repressor and the operator.
