Two clustered 8-oxo-7,8-dihydroguanine (8-oxodG) lesions increase the point mutation frequency of 8-oxodG, but do not result in double strand breaks or deletions in Escherichia coli
Multiply damaged sites (MDSs) are generated in DNA by ionizing radiation. In vitro studies predict that base excision repair in cells will convert MDSs to lethal double strand breaks (DSBs) when two opposing base damages are situated ≥2 bp apart. If the lesions are situated immediately 5′ or 3′ to e...
