.Gene regulation governing lactose operon of E.coli
that involves the lac I gene product is
(a) negative and repressible because repressor
protein prevents transcription
(b) feedback inhibition because excess of
β-galactosidase can switch off transcription
(c) positive and inducible because it can be induced
by lactose
(d) negative and inducible because repressor
protein prevents transcription.
