In the case of lac operon, the gene expression is inhibited by __________

In the case of lac operon, the gene expression is inhibited by __________ Correct Answer Interaction of repressor with operator

In the case of lac operon, the gene expression is inhibited by the interaction of repressor with operator, as repressor does not bind to lactose. The presence of lactose leads to the interaction of lactose with operator which induces the activity of the operon.
