Transcriptional control that acts by regulating the continuation of transcription is called:
A) riboswitching.
B) antitermination.
C) negative control.
D) operator mutation.
E) attenuation.

Question

Quizplus · Accepted Answer

Attenuation is a transcriptional control mechanism that regulates the continuation of transcription. It involves the formation of a terminator hairpin structure in the nascent RNA transcript, which blocks the progression of RNA polymerase and terminates transcription.
