Gene regulation governing lactose operon of E. coli that involves the lac I gene product is:-
- Negative and inducible because repressor protein prevents transcription
- Negative and repressible because repressor protein prevents transcription
- Feedback inhibition because excess of \(\beta\)-galactosidase can switch off transcription
- Positive and inducible because it can be induced by lactose
Answer
(A) Negative and inducible because repressor protein prevents transcription
