WebThe loss of 3' to 5' exonuclease activity causes replication fidelity problems. In other words, the polymerase will not fix its flaws, ... polymerases are necessary. To conclude the replication procedure on time, speed is key. RNA polymerases generally transcribe just a tiny portion of each chromosome. WebJul 25, 1975 · The lambda exonuclease, an enzyme that has been implicated in genetic recombination, rapidly and processively degrades native DNA, starting at the 5' terminus. …

DNA polymerase I also has 3' to 5' and 5' to 3' exonuclease activity, which is used in editing and proofreading DNA for errors. The 3' to 5' can only remove one mononucleotide at a time, and the 5' to 3' activity can remove mononucleotides or up to 10 nucleotides at a time. See more Exonucleases are enzymes that work by cleaving nucleotides one at a time from the end (exo) of a polynucleotide chain. A hydrolyzing reaction that breaks phosphodiester bonds at either the 3′ or the See more RNA polymerase II is known to be in effect during transcriptional termination; it works with a 5' exonuclease (human gene Xrn2) to degrade the newly formed transcript downstream, leaving the polyadenylation site and simultaneously shooting the polymerase.
