A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study.

These stalled replication forks appear in many types of DNA damage, explaining the broad role of the D2-I complex in other forms of DNA repair as well as via the FA pathway.

Experiments in flies and other model systems reveal that retrotransposons ‘hijack’ a DNA-repair pathway in host cells to produce circular DNA, enabling their replication and subsequent ...

In a new study reported in Frontiers in Cell and Developmental Biology, scientists used a bacterial model to show that in zero gravity, the enzymes that copy DNA are not as accurate as they are under ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified.

Researchers have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than ...

The whole process of DNA replication, in human cells, takes about eight hours. There is still plenty to be worked out. For one thing, the DNA that’s being copied is not a naked double helix.

The cell controls the start of DNA replication in a two-step process. The whole goal of the process is to control the actions of a crucial enzyme—called a helicase—that unwinds the DNA double ...

Northwestern Medicine scientists have discovered how a common virus linked to birth defects and chronic illness manipulates ...
