Attenuation of RNA Involves the Formation of Alternate Stem-Loop Structures

Question

Attenuation of RNA involves the formation of alternate stem-loop structures.

Accepted Answer

Attenuation of RNA involves the formation of alternate stem-loop structures. During transcription, the nascent RNA strand folds back on itself to form a hairpin loop. Depending on the sequence and length of the loop, it can either terminate transcription or allow it to continue. This process is known as attenuation and is commonly found in bacterial gene regulation.
