Abasic lesions, which are formed endogenously and as a consequence of exogenous agents, are lethal and mutagenic. Hydrogen atom abstraction from C2‘ in DNA under aerobic conditions produces an oxidized abasic lesion (C2-AP), along with other forms of DNAdamage. The effects of C2-AP on DNA structure and function are not well understood. A method for the solid-phase synthesis of oligonucleotides containing
