A mutation in the lacI gene prevents the gene product from binding allolactose. What will the expression level of the operon be in the absence of lactose?

Question

Quizplus · Accepted Answer

In the absence of lactose, the lacI gene product (the repressor) will bind to the operator, preventing transcription of the operon. If the repressor cannot bind allolactose, it will not be inactivated, leading to no transcription.
