Synthesis of a repressible enzyme is stopped by the
A) substrate binding to the repressor.
B) end product binding to the promoter.
C) corepressor binding to the operator.
D) corepressor- repressor complex binding to the operator.
E) allosteric transition.

Question

Quizplus · Accepted Answer

The synthesis of a repressible enzyme can be stopped by a complex of corepressor and repressor protein binding to the operator. This binding prevents RNA polymerase from transcribing the genes responsible for the enzyme production.
