RNA polymerase is an enzyme which catalyzes the addition of a ribonucleoside triphosphate to the 3′ – end of a RNA strand using a template. The systematic name of this enzymatic activity is nucleoside triphosphate-RNA nucleotidyltransferase, and the catalyzed reaction can be represented as
$$ \mathrm{nucleoside}\ \mathrm{triphosphate}+{\mathrm{RNA}}_n=\mathrm{diphosphate}+{{\mathrm{RNA}}_n}_{+1} $$
