A cis-acting DNA sequence that modulates the basal rate of transcription of a gene is termed a(n)
A)repressor.
B)activator.
C)promoter.
D)enhancer.
E)initiator.

Question

Quizplus · Accepted Answer

The definition in the question matches that of an enhancer, which is a cis-acting DNA sequence that increases the rate of transcription of a gene. Repressors can decrease the rate of transcription, activators can increase it, promoters are necessary for transcription to start, and initiators are transcription factors that bind to the promoter region to initiate transcription.
