How does rna polymerase read dna

Web"RNA polymerases are enzymes that transcribe DNA into RNA. Using a DNA template, RNA polymerase builds a new RNA molecule through base pairing. For instance, if there is a G in the DNA template, RNA polymerase will add a C to the new, growing RNA strand. RNA polymerase always builds a new RNA strand in the 5’ to 3’ direction." Translation WebAug 22, 2024 · A strand of DNA is read by the RNA polymerase in 3’-5’ direction and its RNA transcript is synthesized in the 5’-3’ direction.
