In negative control of transcription, how does the presence of an inducer affect transcription? The inducer binds to the operator. The inducer does not bind to the operator. The inducer causes the repressor to bind to the operator. The inducer prevents the repressor from binding to the operator?

The inducer prevents the repressor from binding to the operator

Explanation:

The repressor is bound to the operator, when the inducer binds to the repressor it produces a change in the shape of this that causes the dissociation of the operator from the repressor. This change allows the ARN polymerase to bind with the promoter in order to start transcription.
