When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among ...

This illustration shows proteins and DNA in the process of DNA repair. RecA proteins (gold) cradle a single-stranded DNA (brown) that searches for homology with a DNA template (purple). The template ...

An international research team has identified a human protein, ANKLE1, as the first DNA-cutting enzyme (nuclease) in mammals ...

Tampa (BLOOM) – Understanding the intricate process of aging has been a subject of fascination for scientists and researchers. While aging is a natural part of life, recent studies have shed light on ...

A DNA repair process, DNA charge transport, has been implicated in some cancers. An electron travels from one protein (blue) to the next (green) and adds to the protein’s iron-sulfur cluster. With the ...

An elegant collaboration between researchers in the UK's two core-funded Medical Research Council Research Institutes, the Laboratory of Medical Sciences (LMS) in London and the Laboratory of ...

Meet the newest (probationary) member of the Office of the Chief Medical Examiner: a cooler-sized gizmo called ANDE, which the agency says will turbocharge the process of identifying John and Jane ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

High concentrations of the stress hormone, Cortisol, in the body affect important DNA processes and increase the risk of long-term psychological consequences. These relationships are evident in a ...

Cancer’s most catastrophic DNA damage has long looked like a crime scene without a culprit, with chromosomes shattered and ...

As officials wrap up the process of recovering bodies of Conception victims, they are moving to the next step — identifying their remains. Authorities say most if not all of those killed in Monday’s ...
