Question

What is the role of RNA polymerase?

Answer 1

It uses a single-stranded DNA template to synthesize a complementary strand of RNA.

Step-by-step explanation:

It is the main enzyme involved in transcription and builds an RNA strand in the 5' to 3' direction.

Answer 2

-binds to DNA during transcription and separates the DNA strands
-then uses one strand of DNA as a template from which to assemble nucleotides into a complementary strand of RNA. Hope this helped. ;)
