What does the repressor bind to?

In molecular genetics, a repressor is a DNA- or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers. A DNA-binding repressor blocks the attachment of RNA polymerase to the promoter, thus preventing transcription of the genes into messenger RNA.Click to see full answer. Accordingly, what does the lac repressor bind to?The lac repressor protein binds to the operator and blocks RNA polymerase from binding to the promoter and transcribing the operon. The promoter is the binding site for RNA polymerase, the enzyme that performs transcription. The operator is a negative regulatory site bound by the lac repressor protein.Subsequently, question is, do repressors bind to enhancers? Transcriptional repressors can bind to promoter or enhancer regions and block transcription. Like the transcriptional activators, repressors respond to external stimuli to prevent the binding of activating transcription factors. Just so, where does a repressor bind? A repressor is a protein that binds to a short specific DNA sequence and controls the expression of a gene or operon. A repressor is a negatively acting regulatory protein. It binds to the operator region of a promoter and thereby negatively influences the ability of RNA polymerase to transcribe the gene or operon.What is the role of the repressor molecule in operon function?repressor molecule activates repressor protein so genes can function. What happens when a repressor is bound to the operator? It switches off the operons if in active form (negative control)
