New insights into DNA repair

A new paper in the prestigious journal Nature from Brandeis researchers in the laboratory of James Haber provides a detailed description of the processes of DNA repair.

Chromosomes undergo DNA repair to correct insults to our genetic code, caused either by errors in copying the DNA or by external factors such as exposure to radiation or toxins. Most damage gets accurately repaired, so the cell is unaffected, but some result in permanent errors (mutations or chromosome rearrangements) that may lead to diseases, including cancer. Especially dangerous are double-strand DNA breaks (DSB’s) that sever the chromosome.

The work was principally carried out by postdoctoral fellow Ranjith Anand with contributions by technician Annette Beach and physics Phd student Kevin Li. They examined repair of a double-strand break in yeast cells.
