it is proposed that ( a ) some dna lesions introduced by any dna damaging agent may be close enough to interfere with constitutive repair replication of each other , ( b ) these lesions induce a repair system ( sos repair ) which involves the reca+ lexa+ and polc+ genes ( c ) repair and concomitant mutagenesis occurs during repair replication by the insertion of mismatched bases opposite the noncoding dna lesions .
