B) polymerases
C) short tandem repeats
D) introns

Question

Quizplus · Accepted Answer

Enhancers are segments of DNA that increase the rate of transcription of certain genes by binding to transcription factors and promoting the binding of RNA polymerase to the promoter region. Polymerases are enzymes that catalyze the formation of RNA from a DNA template, but they don't necessarily increase the rate of transcription. Short tandem repeats are repeating sequences of DNA that are used in DNA profiling, and introns are non-coding segments of DNA that are transcribed but later removed from the mature RNA molecule.
