WebInducer. In molecular biology, an inducer is a molecule that regulates gene expression. [1] 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.
