Question

Quizplus · Accepted Answer

Proteins that bind to DNA and turn on operons by making it easier for RNA polymerase to bind to a promoter are called activators. Regulators typically refer to molecules that control gene expression, while operators are specific DNA sequences that are bound by repressors or activators to regulate transcription. Repressors bind to operators to prevent transcription from occurring.
