A scientist compares the promoter regions of two genes. Gene A’s core promoter plus proximal promoter elements encompasses 70bp. Gene B’s core promoter plus proximal promoter elements encompasses 250bp. Which of the scientist’s hypotheses is most likely to be correct?

a) More transcripts will be made from Gene B.
b) Transcription of Gene A involves fewer transcription factors.
c) Enhancers control Gene B’s transcription.
d) Transcription of Gene A is more controlled than transcription of Gene B.
