Question

What is the role of RNA polymerase in transcription?
It binds to the promoter region of a gene and adds new nucleotides to the growing end of nascent mRNA.
It binds to the promoter region of a gene and terminates the process of transcription.
It binds to the coding region and adds nucleotides to the growing end of the DNA

Answer 1

the role of RNa polymerase in transcription is : it binds to  the promoter region of a gene and adds new nucleotides to the growing end of nascent mRNA
It must keep adding nucleotids in order to fully develop  the mRNA to allow for trancription of the cell

hope this helps

Answer 2

Answer:

It binds to the promoter region of a gene and adds new nucleotides to the growing end of nascent mRNA.

Explanation:

RNA polymerase is an enzyme that forms RNA molecules by using information present in DNA template. This process is known as transcription, during which RNA polymerase binds to the promoter region  of DNA or gene and adds new ribonucleotides in growing mRNA chain.

The resulting mRNA molecules provides information for the formation of protein molecules during translation.

Thus, the correct answer is first option.
