2 DNA Pol III enzymes, each comprising α, ε and θ subunits. (It has been proven that there is a third copy of Pol III at the replisome. [1]) the α subunit (encoded by the dnaE gene) has the polymerase activity. the ε subunit has 3'→5' exonuclease activity. the θ subunit stimulates the ε subunit's proofreading.
DNA Polymerase II. (str. K-12 substr. MG1655) DNA polymerase II (also known as DNA Pol II or Pol II) is a prokaryotic DNA-dependent DNA polymerase encoded by the PolB gene. [ 1] DNA Polymerase II is an 89.9-kDa protein and is a member of the B family of DNA polymerases. It was originally isolated by Thomas Kornberg in 1970, and characterized ...
RNA polymerase II holoenzyme. RNA polymerase II holoenzyme is a form of eukaryotic RNA polymerase II that is recruited to the promoters of protein -coding genes in living cells. [1] [2] It consists of RNA polymerase II, a subset of general transcription factors, and regulatory proteins known as SRB proteins [clarification needed] .
Class I – Items of subsistence, e.g., food and forage, which are consumed by personnel or animals at an approximately uniform rate, irrespective of local changes in combat or terrain conditions. Class II – Supplies for which allowances are established by tables of organization and equipment, e.g., clothing, weapons, tools, spare parts ...

This repair polymerase is involved in excision repair with both 3'–5' and 5'–3' exonuclease activity and processing of Okazaki fragments generated during lagging strand synthesis. [21] Pol I is the most abundant polymerase, accounting for >95% of polymerase activity in E. coli ; yet cells lacking Pol I have been found suggesting Pol I ...
RNA polymerase III. In eukaryote cells, RNA polymerase III (also called Pol III) is a protein that transcribes DNA to synthesize 5S ribosomal RNA, tRNA, and other small RNAs. The genes transcribed by RNA Pol III fall in the category of "housekeeping" genes whose expression is required in all cell types and most environmental conditions.
The genome and proteins of HIV (human immunodeficiency virus) have been the subject of extensive research since the discovery of the virus in 1983. [1] [2] "In the search for the causative agent, it was initially believed that the virus was a form of the Human T-cell leukemia virus (HTLV), which was known at the time to affect the human immune system and cause certain leukemias.
