Weak prokaryotic promoters
A) can bind to different transcription factors.
B) have a DNA sequence that is significantly different from that of other common promotors.
C) can be easily bound to $\sigma$ factors.
D) give weak DNA footprinting signals.

Question

Quizplus · Accepted Answer

Weak prokaryotic promoters have sequences that deviate from the consensus sequence, leading to less efficient binding of RNA polymerase and transcription factors, resulting in weaker transcription initiation.
