Strong prokaryotic promoters
A) bind tightly to the transcription factors.
B) have $\sigma$ factors that are larger, more stable proteins.
C) generally result in a higher rate of transcription.
D) are less common in prokaryotes.

Question

Quizplus · Accepted Answer

Strong prokaryotic promoters generally result in a higher rate of transcription. This is because they have a higher affinity for RNA polymerase and other transcription factors, which leads to more efficient initiation of transcription. A and B are incorrect because they do not accurately describe the characteristics of strong prokaryotic promoters, and D is incorrect because strong prokaryotic promoters are actually quite common.
