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.

WebFunction. If an inducer, a molecule that initiates the gene expression, is present, then it can interact with the repressor protein and detach it from the operator. RNA polymerase then can transcribe the message (expressing the gene). A co-repressor is a molecule that can bind to the repressor and make it bind to the operator tightly, which decreases …

WebT7 expression is often very robust but may suffer from undesirable basal (non-induced) transcription especially in DE3 strains.
