When bases are lost by depurination or depyrimidination when bases are modified by alkylation, oxidation, or deamination and when abnormal bases (e.g., dUTP, 8-oxo-dGTP) are incorporated into DNA, the resulting lesions are repaired by base excision repair (BER), which, like NER, can occur via distinct subpathways (see Chapter 1 also see Beard and
