Question

In the lac operon model, lactose molecules function as, inducers, which bind with the operator gene, repressors, which bind with the operator gene, inducers, which bind with the repressor protein, corepressors, which bind with repressor protein

MARKS App · Accepted Answer

Lactose or lac operon of E. coli is an example of inducible operon. Lactose is known to be the inducer and substrate for the enzyme β -galactosidase. It binds with the repressor protein and changes it into a non-DNA binding state thus activating the operon.
