B)immediately downstream of the promoter.
C)primarily upstream of the promoter,possibly some distance away.
D)primarily downstream of the promoter,including the exons of the coding region.

Question

Quizplus · Accepted Answer

Enhancer regions can be located upstream of the promoter, sometimes at a considerable distance away, and can even be found within introns. They work by interacting with the promoter region to increase transcriptional activity, so looking upstream of the promoter is the best place to start. Downstream regions and exons are involved in other processes, such as splicing and mRNA stability, and are less likely to contain enhancer elements.
