A) Enhancers are transcription factors; proximal control elements are DNA sequences.
B) Enhancers improve transcription; proximal control elements inhibit transcription.

Question

Quizplus · Accepted Answer

Enhancers are typically located far from the promoter (sometimes tens of thousands of base pairs away), whereas proximal control elements are located closer to the promoter (up to a few hundred base pairs away). This spatial difference is the primary distinction between enhancers and proximal control elements.
