Has a 3' 5' polymerase activity
WebJul 25, 2024 · The polymerase activity would add nucleotides to the free 3' hydroxyl end, growing the new strand in the 5' to 3' direction. The polymerase activity moves forward in a 5' to 3' direction, whereas the exonuclease activity works as a "backspace" and moves "backward" in a 3' to 5' direction. WebJan 5, 2012 · For the 3'-5' polymerase spontaneous hydrolysis is a problem because the triphosphate is on the growing chain. If that one gets hydrolyzed, the whole polymerization needs to be either aborted or the triphosphate need to be readded by some mechanism.

WebThe DNA polymerase activity achieves replication of DNA in a 5´ - 3´ direction and requires deoxyribo-nucleotides triphosphate (dNTPs) and a primer. On the other hand, the 3´ - 5´ exonuclease activity results in proofreading of the new … WebIt has three sites, which provide three distinct catalytic activities: 3′ to 5′ exonuclease, 5′ to 3′ exonuclease, and 5′ to 3′ polymerase.

WebT4 DNA Polymerase catalyzes the synthesis of DNA in the 5´→ 3´ direction and requires the presence of template and primer. This enzyme has a 3´→ 5´ exonuclease activity which is much more active than that found in DNA Polymerase I (E. coli). Unlike E. coli DNA Polymerase I, T4 DNA Polymerase does not have a 5´→ 3´ exonuclease function. WebHowever, no polA mutant has been identified that is completely deficient in the 5′ 3′ exonuclease activity while retaining 5′ 3′ polymerase activity, of DNA polymerase I. How can these results be explained? Expert Answer 100% (1 rating) 1)Mutation in DNA polymerase 1 gene -Replication continues but the final product may include RNA or …
WebExpert Answer 14) The E.coli Pol III holoenzyme is the major relicative polymerase for both leading and lagging strand.
