Key protein aids in DNA repair
Date:4/11/2010

broken chromosome ends, allowing for much more accurate repair than believed possible.

"This protein actually heals at the nucleotide level as well as the level of the chromosome," says Ramsden, comparing its action to washing and disinfecting a cut before trying to sew it up to promote healing.

The team is hopeful that the discovery of this mechanism for DNA repair may lead to a target for treatment of age-related diseases caused by chromosome damage in the future.
