uv-radiation-induced lesions in dna result in the formation of : ( 1 ) excision gaps ( i.e . a lesion is excised , leaving a gap ) , ( 2 ) daughter-strand gaps ( i.e . a lesion can be skipped during replication , leaving a gap ) , and ( 3 ) double-strand breaks ( i.e . the dna strand opposite a gap can be cut ) .
