up to 80 % of the dna lesions induced by bp and detectable by alkaline sucrose gradient sedimentation may be repaired within 6 h , whereas less than 30 % of the dna damage caused by dmn is apparently removed 24 h after treatment , implying that dna repair may be involved in the differential lethality of cho cells exposed to dmn and bp .
