This can occur chemically when a hydroxyl (OH-) free radical reacts with a hydrogen atom and forms hydrogen peroxide (H 2 O 2 ). It is fairly easy to repair damage like this if the complementary (or opposite) strand is undamaged.

WebCTCF is a nuclear protein initially discovered for its role in enhancer-promoter insulation. It has been shown to play a role in genome architecture and in fact, its DNA binding sites are enriched at the borders of chromatin domains. Recently, we showed that depletion of CTCF impairs the DNA damage response to ionizing radiation. To investigate the relationship …
