title: [Repair of embichin-induced DNA damage in embryonal fibroblasts of 101/H and CBA mice].
abstract: The changes in the molecular weight of DNA one-strand fragments were studied after a short-term incubation of 101/H and CBA mouse cells with embichin (nitrogen mustard). Unlike CBA mouse cells in which the repair of DNA lesions is completed after 24 hours, DNA in 101/H mouse cells was shown to be strongly fragmented. It is assumed that the deficiency of the repair of DNA lesions induced by embichin in 101H/ mouse cells is due to the deficiency of the last stage of excision repair, namely of the ligase reaction or to the uncoordinated pattern of the endonuclease and ligase reactions.
