A DNA sequence is several thousands of nucleotides distant from the promoter.When this sequence is bound by a protein, transcription rates increase greatly.This sequence is most likely a(n)
A) TATA box.
B) enhancer.
C) operon.
D) promoter.
E) consensus sequence.

Question

Quizplus · Accepted Answer

Enhancers are regulatory sequences that are often located far away from the promoter of a gene and bind with specific transcription factors, which greatly increase transcription rates. TATA box, promoter, operon, and consensus sequence are all related to gene expression regulation, but they are not typically located far away from the promoter like enhancers.
