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