WEBNov 17, 2020 · RNA polymerase II (Pol II) is an essential, multi-subunit, DNA-dependent, nucleotidyltransferase. In eukaryotes, Pol II is the one of three nuclear RNA polymerases. It is responsible for unspooling the genetic program in the form of protein-coding mRNAs and some small non-coding RNAs.
DNA Polymerase II - an overview | ScienceDirect Topics
WEBDNA polymerase II (pol II) is a single polypeptide of 783 amino acids with a predicted mass of 89.9 kDa, and is encoded by the polB (a.k.a. dinA) gene. DNA pol II is the founding member of the B family of DNA polymerase structures, and contains the five motifs characteristic of this family, including both DNA polymerase and exonuclease domains.
