In negative operon

Question

In negative operon (A) Inducer binds with repressor (B) Co-repressor does not bind with repressor (C) Co-repressor binds with inducer (D) cAMP have negative effect on lac operon

Tardigrade Admin · Accepted Answer

The repressor is a protein produced by the regulator gene in the operon, which binds to the operator and stops the RNA polymerase to transcribe the structural genes. Hence, the repressor acts negatively in controlling the gene expression.
