How are RNA Hairpin Turns Related to Termination

Question

How are RNA hairpin turns related to termination?
A) Release factors bind to sites on the hairpin turn, causing release of the RNA transcript.
B) The turns are formed from complementary base pairing and cause separation of the RNA transcript and RNA polymerase.
C) The hairpin turn prevents more nucleoside triphosphates from entering the active site of the enzymes, effectively shutting off the process of polymerization.
D) A three- base repeat signals a stop sequence, and the RNA transcript is released.

Accepted Answer

Hairpin turns in RNA are formed by complementary base pairing within the RNA molecule itself. This structure can cause the RNA polymerase to pause or dissociate from the RNA, leading to the termination of transcription.
