Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

CDT1 inhibits the helicase activity of the MCM complex, thereby suppressing nascent strand synthesis in DNA replication in cultured human cells. This action results in fork collapse and DNA damage, ...

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

Unrepaired DNA-protein crosslinks (DPCs) – highly toxic tangles of protein and DNA – cause a process that leads to premature ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

A new mouse study found that unrepaired DNA-protein crosslinks activate inflammatory signaling pathways that trigger early aging disorders.

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...
