What is the regulation of a lac operon by a repressor known as? Correct Answer Negative regulation

The regulation of a lac operon by the repressor is known as negative regulation. At rare occasions, lac operons are also observed to be under the control of positive regulation. In negative regulation, the operon cannot transcribe the RNA polymerase enzyme.
