Any regulatory protein that acts by preventing transcription termination is called a:
A)corepressor.
B)coactivator.
C)antiterminator.
D)antipromoter.
E)attenuator.

Question

Quizplus · Accepted Answer

An antiterminator is a regulatory protein that prevents transcription termination from occurring. This allows the RNA polymerase to continue transcribing beyond the termination site to produce a longer RNA molecule. Corepressors and coactivators, on the other hand, work to regulate gene expression by either inhibiting or enhancing transcription initiation. Antipromoters are DNA sequences that specifically inhibit transcription initiation. Attenuators are regulatory regions in bacterial operons that can cause premature termination of transcription under certain conditions, resulting in the production of a shorter RNA molecule.
