If the lac operon of the genome of bacteria is always active it has a defect in which region of the operon?

If the lac operon of the genome of bacteria is always active it has a defect in which region of the operon? Correct Answer i

Mutants that fail to make a functional i gene product result in constitutive expression of the operon even when lactose is not available. This result implies that the normal i gene product is a repressor, which blocks transcription when bound to o.
