What is DNA Polymerase? The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from one original DNA molecule. During this process, DNA polymerase âreadsâ the existing DNA strands to create two new strands that match the existing ones.
A: The function of RNA polymerase II is  to synthesize mRNA using a DNA strand as a template, explains UC Davis BioWiki. The process, by which an mRNA strand is constructed from a DNA strand, is called transcription, and the product is called a primary transcript, notes North Dakota State University.
