Frequency (%) of micronuclei in primary cultures of mouse embryo fibroblasts with indicated genotypes of DNAPKcs +/+, DNAPKcs +/-, or DNAPKcs -/- assayed without or with transfection of a Tax plasmid. *** indicates significantly different value (P < 0.001, G test) from that in DNAPKcs +/+ cells, with or without transfect with Tax plasmid. ** indicates significantly different value (P < 0.01, G test) from that in DNAPKcs +/+ cells without transfection with Tax plasmid.
