RNA polymerase (Pol) II catalyses DNA-dependent RNA synthesis during gene transcription. There is, however, evidence that Pol II also possesses RNA-dependent RNA polymerase (RdRP) activity. Pol II can use a homopolymeric RNA template, can extend RNA by several nucleotides in the absence of DNA, and has been implicated in the replication of the RNA genomes of hepatitis delta virus (HDV) and plant viroids ...
