In an inducible operon, the repressor protein in its native conformation binds to what? The co-repressor molecule The regulatory gene The operator region The IRES The DNA polymerase

In an inducible bacterial operon, what is the effect of the binding of the inducer molecule to the repressor protein? Inhibits the binding of the repressor protein to the operator and activates gene transcription Promotes the binding of the repressor protein to the operator and blocks gene transcription Has no effect on the binding of the repressor to the operator and transcription Inhibits the binding of DNA polymerase to the operator Promotes the splicing of the mRNA
