| DNA-Directed RNA Polymerases DNA-Dependent RNA Polymerases | RNA Polymerases | Transcriptases | DNA-Directed RNA Polymerase | RNA Polymerase | Transcriptase | DNA Dependent RNA Polymerases | DNA Directed RNA Polymerase | DNA Directed RNA Polymerases | Polymerase, RNA Enzymes that catalyze DNA template-directed extension of the 3'-end of an RNA strand one nucleotide at a time. They can initiate a chain de novo. In eukaryotes, three forms of the enzyme have been distinguished on the basis of sensitivity to alpha-amanitin, and the type of RNA synthesized.
