WebIn the lac operon, the repressor inhibits transcription when a. the repressor is bound to the inducer. b. the repressor is not bound to the inducer. c. the repressor is bound to glucose. d. the repressor is not bound to the operator. In molecular biology, an inducer is a molecule that regulates gene expression. An inducer functions in two ways; namely: By disabling repressors. The gene is expressed because an inducer binds to the repressor. The binding of the inducer to the repressor prevents the repressor from binding to the operator.
