WebThe DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from one original DNA molecule. What are the proofreading activity of DNA pol 3? WebDifferent DNA polymerases perform specific functions. In prokaryotes, DNA polymerase III is the main enzyme responsible for replication. DNA polymerase I and II have a role to play in repair, removing the primer and filling the gaps. In eukaryotes, DNA polymerase 𝝳 is the main enzyme for replication.

WebDNA Pols for DNA Replication DNA pols that are mainly responsible for the duplication of entire genomes are called ‘replicative’ enzymes. In both prokaryotes and eukaryotes, DNA replication is discontinuous, thus requiring more than one DNA pol to coordinately replicate the continuous (leading) and discontinuous (lagging) DNA strand. WebPol III catalyzes the formation of phosphodiester linkages between nucleotides. Once the hydrogen bond has been formed between the bases, the other other nucleotide attacks to get rid of two of the attached phosphates. This results in a pyrophosphate. Pol III stays bound to the replication fork DNA replication proceeds at around 1000 bp/sec.
