Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...

QUICK FIX: From left, Frederick Alt and Guillermo Taccioli and their colleagues identified DNA-dependent kinase as a key enzyme involved in DNA repair. The way that DNA repairs itself recently has ...

New study shows that cancer damages its own DNA by pushing key genes to work too hard. Researchers found that the most ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the effects aren't just skin deep. Inside the body, DNA is literally being torn ...

Cars patched up after a wreck may look fixed—but never run quite as before. The same may hold true for chromatin, according to a study published in Science on November 6. In response to double-strand ...

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists have discovered a protein that can directly halt DNA damage. Better yet, a new study shows it appears to be 'plug and ...

RNA’s Surprising Role in DNA Repair New insights could lead to improved treatments for cancer and other diseases. Francesca Storici and her research team discovered a surprising role for RNA in DNA ...

Objectives Understanding the molecular changes in the preclinical synovium is crucial for identifying factors that drive arthritis development. Persistent DNA damage in tissues is known to drive a ...
