(Nanowerk News) For the first time, it is possible to follow, step-by-step and with atomic resolution, what happens when the enzyme DNA photolyase repairs ultraviolet light-induced DNA damage. An ...

Reporting in Nature, scientists have identified a novel process that protects the ends of chromosomes from incorrectly applied DNA repair.. | Cell And Molecular Biology ...

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 ...

Researchers have revealed the structural mechanisms of a major DNA repair pathway in human cells. The research, published today as a Reviewed Preprint in eLife, is described by the editors as a ...

DNA lesions are repaired by a cut-and-remove process called nucleotide excision repair. An in vitro biochemically defined system has been developed in which six repair factors are sufficient to excise ...

A new discovery offers hope for Huntington’s disease. This discovery provides hope that a DNA repair process may help slow or stop disease progression. Research has identified a critical DNA repair ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the ...

Ultraviolet (UV) rays from sunlight can cause DNA damage that leads to skin aging and cancer. Fortunately, our bodies have a highly efficient repair system capable of swiftly identifying and repairing ...

Extremophiles are a favorite tool of astrobiologists. But not only are they good for understanding the kind of extreme ...
