The primary difference between enhancers and promoter-proximal elements is that enhancers ________.
A) are transcription factors; promoter-proximal elements are DNA sequences
B) enhance transcription; promoter-proximal elements inhibit transcription
C) are part of the promoter; promoter-proximal elements are regulatory sequences distinct from the promoter
D) are at considerable distances from the promoter; promoter-proximal elements are close to the promoter
E) are DNA sequences; promoter-proximal elements are proteins

Question

Quizplus · Accepted Answer

Enhancers are located at considerable distances away from the promoter region, whereas promoter-proximal elements are located close to the promoter region. Enhancers can stimulate transcription from afar, whereas promoter-proximal elements work in conjunction with the promoter to initiate transcription.
