Which statement about transcriptional termination in prokaryotes is false?
A) Termination is signaled by transcription of a GC-rich interval.
B) Transcription terminates when the RNA polymerase dissociates from its DNA template.
C) The ribosome comes to a UAA, UAG, or UGA stop codon, and transcription ceases.
D) A segment of RNA forms a stable stem-loop structure by complementary base pairing.

Quizplus · Accepted Answer

While UAA, UAG, and UGA are stop codons in translation, they have no effect on transcriptional termination in prokaryotes. Transcriptional termination in prokaryotes is signaled by transcription of a GC-rich interval, and a segment of RNA forms a stable stem-loop structure by complementary base pairing. The RNA polymerase then dissociates from its DNA template to terminate transcription.
