Which of the following statements is true?
A) RNA polymerase I is used to synthesize tRNA.
B) RNA polymerase III is used to transcribe mRNA.
C) RNA polymerase II is used to transcribed rRNA.
D) RNA polymerase binds enhancers.
E) Enhancers are transcription elements.

Question

Quizplus · Accepted Answer

Enhancers are DNA sequences that bind transcription factors to enhance transcription. They are not RNA polymerases and do not directly participate in transcription. Therefore, the only true statement is that enhancers are transcription elements. The other statements are false: RNA polymerase I is used to transcribe rRNA, RNA polymerase III is used to transcribe tRNA and other small RNAs, RNA polymerase II is used to transcribe mRNA, and RNA polymerase does bind to enhancers but enhancers themselves are not RNA polymerases.
