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.

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] .

Aug 8, 2023 · DNA Polymerase 2. Prokaryotic organisms like bacteria include an enzyme called DNA polymerase II (Pol II) that is used in the replication and repair of DNA. It belongs to the family of DNA polymerase B, which also includes a number of other DNA polymerases discovered in bacteria and archaea.

RNA polymerase II (Pol II) transcribes all protein-coding genes and many noncoding RNAs in eukaryotic genomes. Although Pol II is a complex, 12-subunit enzyme, it lacks the ability to initiate transcription and cannot consistently transcribe through long DNA sequences.

Jun 1, 2024 · DNA polymerase II (DNA Pol II), also referred to as Pol II, is a DNA-dependent DNA polymerase found in prokaryotic organisms. Encoded by the PolB gene, DNA Pol II plays a crucial role in DNA replication and repair processes within these microorganisms.

DNA 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.

Oct 10, 2024 · DNA Polymerase II is an enzyme involved in DNA replication, synthesizing new DNA strands and correcting errors to maintain genomic integrity. Understanding its structure and function provides insights into cellular processes and …

DNA polymerase II is a family B polymerase encoded by the polB gene. Pol II has 3'–5' exonuclease activity and participates in DNA repair , replication restart to bypass lesions, and its cell presence can jump from ~30-50 copies per cell to ~200–300 during SOS induction.

Mar 1, 2021 · DNA polymerase II is a member of the B family of DNA polymerases. It is involved both in replicative and reparative processes, particularly in a 5’ 3′ DNA-dependent DNA polymerase activity and in 3’ 5′ exonuclease proofreading activity.

Jun 3, 2023 · DNA Polymerase II. It belongs to Type B or Family B of the polymerases. Its major function is the 3′ – 5′ exonuclease activity and to also restart replication after replication stops due to DNA strand damages. The DNA polymerase II is found in the replication fork, to help in directing the activities of other polymerases. DNA Polymerase III
