attenuation is a transcriptional control mechanism that relies on A) attenuator

Question

attenuation is a transcriptional control mechanism that relies on A) attenuator molecules binding to mRNA B) effector proteins to control the mRNA self-binding interactions C) transcriptional feedback inhibition D) mRNA self-complementarity attenuation is a transcriptional control mechanism that relies on A) attenuator molecules binding to mRNA B) effector proteins to control the mRNA self-binding interactions C) transcriptional feedback inhibition D) mRNA self-complementarity attenuation is a transcriptional control mechanism that relies on A) attenuator molecules binding to mRNA B) effector proteins to control the mRNA self-binding interactions C) transcriptional feedback inhibition D) mRNA self-complementarity

Explanation / Answer

B) effector proteins to control the mRNA self-binding interactions

The attenuator is the effector protein that binds the mRNA and initiates the formation of hairpin-loop structure through intramolecular folding. Attenuator molecules along binding to the mRNA does not lead to loop formation. mRNA complementarity is not responsible for loop formation.
