Preferred Label : DNA-Directed RNA polymerases;
MeSH definition : 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. (From Enzyme Nomenclature, 1992).;
