The function of DNA polymerase is to replicate, proofread and repair DNA. Several DNA polymerases exist, but DNA polymerase I, or Pol I, and DNA polymerase III, or Pol III, are the main ones involved in DNA replication. More »

The enzyme DNA polymerase III is the primary enzyme involved with bacterial DNA replication. It performs the 5'-3' polymerase function, which means that it adds nucleotides to the 3' end of the forming DNA strand during ... More »

The function of RNA polymerase II is to synthesize mRNA using a DNA strand as a template, explains UC Davis BioWiki. The process, by which an mRNA strand is constructed from a DNA strand, is called transcription, and the... More »

The most basic difference between DNA polymerase and RNA polymerase is that DNA polymerase is used in the replication of DNA, while the RNA polymerase transcribes DNA to RNA. DNA polymerase also makes fewer mistakes than... More »

DNA polymerase II is a type of DNA polymerase: a category of enzymes that synthesize identical copies of existing DNA, allowing dividing cells to pass this genetic information on to their daughter cells. DNA polymerase I... More »

Many enzymes are involved in DNA replication, including DNA helicase, DNA polymerase, topoisomerase, DNA gyrase, DNA ligase, primase and telomerase. Replication is a complex process with many steps, all of which require ... More »
