RNA polymerase II (RNAP II and Pol II) is a multiprotein complex that transcribes DNA into precursors of messenger RNA (mRNA) and most small nuclear RNA (snRNA) and microRNA. [1] [2] It is one of the three RNAP enzymes found in the nucleus of eukaryotic cells. [3] A 550 kDa complex of 12 subunits, RNAP II is the most studied type of RNA polymerase.
RNAP not only initiates RNA transcription, it also guides the nucleotides into position, facilitates attachment and elongation, has intrinsic proofreading and replacement capabilities, and termination recognition capability. In eukaryotes, RNAP can build chains as long as 2.4 million nucleotides.

Few PBMs are independently owned and operated. PBMs operate inside of integrated healthcare systems (e.g., Kaiser Permanente or Veterans Health Administration), as part of retail pharmacies, major chain drug stores (e.g., CVS Pharmacy or Rite-Aid), and as subsidiaries of managed care plans or insurance companies (e.g., UnitedHealth Group).
