A)upstream of the gene enhanced.
B)downstream of the gene enhanced.
C)within the introns of other genes.
D)proximal to the gene enhanced.
E)upstream or downstream of the gene enhanced,even within the introns of other genes.

Question

Quizplus · Accepted Answer

Enhancers are regulatory DNA sequences that can increase the transcription of a gene. They can be located upstream or downstream of the gene they enhance, and they can also be found within the introns of other genes. Their position is not strictly fixed relative to the gene they regulate, and they can act over long distances.
