Web10 Jul 2024 · Replication. New cells are continuously forming in the body through the process of cell division. For this to happen, the DNA in a dividing cell must be copied in a process known as replication. The complementary base pairing of the double helix provides a ready model for how genetic replication occurs.

WebT4 DNA Polymerase is a DNA-dependent DNA polymerase that catalyzes the addition of deoxynucleoside-5′-triphosphates to the hydroxyl termini of recessive ends. The enzyme has a very active 3′→5′ exonuclease with a high specificity for single-stranded DNA; it lacks 5′→3′ exonuclease activity.

The findings, which were … WebRecently, we showed that the nucleoside analog 1-β-d-arabinofuranosylcytosine (Ara-C) was a potent inhibitor of BDV. This finding was surprising for an RNA virus, since Ara-C is a DNA polymerase inhibitor. Thus, we sought to better define the mechanism of action of Ara-C on BDV. Here, we show that (i) this effect is specific for an arabinoside…
