The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, ... Before replication occurs, an enzyme called helicase unwinds the DNA molecule from its tightly woven form.

This study reveals how SV40 helicase unwinds DNA, highlighting ATP hydrolysis's role in translocation and offering insights into viral replication mechanisms.

DNA replication is a complex process in which a helicase ring separates the DNA molecule's two entwined and encoded strands, allowing each to precisely reproduce its missing half.

Indeed, DDX3X was enriched at DNA breaks following restriction enzyme cutting, further substantiating their hypothesis that this helicase might have direct involvement in the DNA damage response.

But the gaps are made up because at some opportunity the lagging strand polymerase can go fast. But the other problem is that if the polymerase stops the helicase that unwind DNA ahead of it creates ...
