Question

Quizplus · Accepted Answer

The site on DNA to which the repressor protein binds is called the operator. It is located near the promoter region of an operon and is responsible for regulating the transcription of genes within the operon. The repressor protein binds to the operator and prevents RNA polymerase from transcribing the genes, thus inhibiting gene expression.
