Question

How does the operon function in the presence of lactose?

Answer in Brief

Solution

  1. Lactose induces the lac operon. The regulatory gene is activated when lactose is added to the bacteria's medium.
  2. The inducer binds to the repressor protein, rendering it inactive, allowing transcription of the operon.
  3. Thus, the lac operon is negatively regulated in this case.
