The function of rho requires:
A) a stretch of uridines
B) GC-rich region followed by uridines
C) pause sites and GC-rich regions
D) pause sites and stretches of uridines
E) a helicase to unwind it from the RNA

Question

Quizplus · Accepted Answer

Rho-dependent termination requires the presence of pause sites, which cause the RNA polymerase to pause briefly during transcription. These pause sites are commonly followed by stretches of uridines, which allow Rho to bind and participate in termination. Therefore, the function of rho requires pause sites and stretches of uridines together, making option D the best choice.
