What is the role of RNA polymerase in transcription?

AIt binds to the promoter region of a gene and adds new nucleotides to the growing end of nascent mRNA.
BIt binds to the promoter region of a gene and terminates the process of transcription.
CIt binds to the coding region and adds nucleotides to the growing end of the DNA.

Verified Answer :

C. It binds to the coding region and adds nucleotides to the growing end of the DNA.

Answer:

The answer is A

Explanation:

RNA polymerase binds to the promoter region, so C is out. I'm not sure how to explain why B is out, but trust me it's A.
