How are the structural genes inactivated in lac operon in E. Coli? Explain.

Text Solution

Verified by Experts

In the absence of lactose, no inactivation ofrepressor occurs and hence the repressor binds to the operator region of the operon, thus preventing RNA polymerase from transcribing the operon thus, inactivation of the production of structural genes in E. coli occurs.
