Abstract excerpt
The loss of bases from cellular DNA occurs via both spontaneous and mutagen-induced reactions. The resulting apurinic/apyrimidinic (AP) sites are cytotoxic and mutagenic but are counteracted by repair initiated by AP endonucleases. Previously, in vitro and bacterial transfection studies suggested...
