E)UV-protection responses.

Question

Quizplus · Accepted Answer

Attenuator control is a regulatory mechanism primarily found in amino acid biosynthetic pathways in bacteria. It involves premature termination of transcription in response to the availability of the end product of the pathway, thereby preventing the synthesis of enzymes when they are not needed.
