Prokaryotic transcription could terminate by
A) association of a $\sigma$ factor with the DNA.
B) RNA with GC stem loop structures.
C) a G-rich region on the DNA.
D) RNA polymerase without the elongation factor.

Question

Quizplus · Accepted Answer

Prokaryotic transcription termination often involves the formation of an RNA hairpin with GC stem loop structures that destabilize the RNA-DNA-RNA polymerase complex, leading to transcription termination. Choices A, C, and D are not accurate descriptions of prokaryotic transcription termination.
