B)The ability of pre-mRNA to be properly spliced would change.
C)The ability of mRNA to be translationally regulated would change.
D)The amino acid sequence of the translated protein would be altereD.
E)The rate of transcription may increase or decreasE.

Question

Quizplus · Accepted Answer

Mutations in the promoter region can affect the binding of RNA polymerase and therefore affect the rate of transcription. This can either increase or decrease the rate of transcription, ultimately affecting the amount of mRNA and protein synthesized. None of the other choices specifically describe the effect of a promoter mutation.
