What Action Results When Activators Present near a Gene Are

Question

What action results when activators present near a gene are "turned on"?
A) increased transcription
B) decreased gene expression
C) unwinding of the DNA double helix
D) a shift in the reading frame

Accepted Answer

Activators are molecules that bind to regulatory sequences near a gene and stimulate transcription by recruiting RNA polymerase and other transcription factors. Turning on activators results in increased transcription of the associated gene.
