What is the role of RNA polymerase? It creates the DNA strand. It bonds the DNA strand. It helps transcribe the DNA strand. It translates the DNA strand.

The role of RNA polymerase is that it helps transcribe the DNA strand. The image shows the process of DNA transcription to make RNA. It can be seen that the RNA polymerase attaches itself to the leading strand of the DNA polymer. It then separates the two DNA strands to make an opening. The RNA polymerase then moves in the 5' to 3' direction to synthesis the RNA molecule.
