RNA polymerase

- RNA synthesis is catalyzed by RNA polymerase, which pries the DNA strands apart and joins together the RNA nucleotides​ - The RNA is complementary to the DNA template strand​ (they pair up) - RNA polymerase does not need any primer​ - RNA synthesis follows the same base-pairing rules as DNA, except that uracil substitutes for thymine​ - RNA polymerase is more functionable than DNA polymerase - it can both open DNA strands and join RNA nucleotides
