Chromatin and DNA damage repair

In eukaryotic cells, inheritance of both exact DNA sequence and its arrangement into the chromatin is critical for maintaining stability of the genome. Various DNA lesions induced by endogenous and exogenous factors make this maintanance problematic. To understand completely how cells resolve this problem the knowledge on the nature of these lesions, their detection, and repair within the chromatin environment should be integrated. Understanding of these processes is complicated by multiple types of DNA lesions and repair pathways, as well as the intricate organization of the chromatin. Recent advances in all these directions help to get insight on the repair regulation of DNA within the chromatin at the molecular and cellular level.
