Term Name:	DNA-directed RNA polymerase activity
Synonyms:	C ribonucleic acid formation factors, C RNA formation factors, deoxyribonucleic acid-dependent ribonucleic acid polymerase activity, DNA-dependent ribonucleate nucleotidyltransferase activity, DNA-dependent RNA nucleotidyltransferase activity, DNA-dependent RNA polymerase activity, DNA-directed RNA polymerase I activity, DNA-directed RNA polymerase II activity, DNA-directed RNA polymerase III activity, nucleoside-triphosphate:RNA nucleotidyltransferase (DNA-directed) activity, RNA nucleotidyltransferase (DNA-directed) activity, RNA polymerase I activity, RNA polymerase II activity, RNA polymerase III activity, RNA polymerase IV activity, RNA polymerase V activity, transcriptase
Definition:	Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template, i.e. the catalysis of DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'.
