Mesh term DNA-Directed RNA Polymerases
Browse to parent terms:RNA Nucleotidyltransferases
Description
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.
