False statement is:

Repressor binds operator gene

Regulator genes produce repressor subunits

IPTG is inducer but not substrate

Regulator gene is inducible

High-Yield Explanation

Ans. D. Regulator gene inducible(Ref: Harper 31/e page 412)Structural genes are inducible, not the regulator genes.Lac I gene produces Repressor subunits.IPTG is an inducer of lac-operon, but itself is not a substrate. This is called gratuitous inducer.
