The Primary Difference Between an Enhancer and a Promoter- Proximal

question 29

Multiple Choice

The primary difference between an enhancer and a promoter- proximal element is that

• A) enhancers are part of the promoter, while promoter- proximal elements are regulatory sequences distinct from the promoter.
• B) enhancers are transcription factors, while promoter- proximal elements are DNA sequences.
• C) enhancers are at considerable distances from the promoter and can be moved or inverted and still function, while promoter- proximal elements are close to the promoter and their position and orientation must be maintained.
• D) enhancers enhance transcription, while promoter- proximal elements inhibit transcription.
• E) enhancers are DNA sequences, while promoter- proximal elements are proteins that bind proximal to the promoter.
