"We have shown, not yet in the cell but in vitro, that the repair of breaks in the other DNA chain, which is "hidden" in the nucleosome, is still possible," said Vasily M Studitsky, professor at Lomonosov Moscow State University.
In higher organisms, DNA is bound with proteins in complexes called the nucleosome. The mechanism of DNA repair opens up new perspectives for the treatment and prevention of neurodegenerative diseases.

Methylated DNA Markers to be Used as Non-invasive Cancer Screening Method
Since the risk of false-positive diagnoses is high in cancer, scientists collected methylated DNA to identify cancerous cells with about 80% accuracy.
