Photochemical and radiochemical reactions of purines may serve as model systems of radiation damage to DNA in living organisms. Elad and co-workers (1) have shown that reactions involving alkylation of the purine bases in nucleic acids are closely paralleled by reactions of caffeine. Although purine
