Abstract: The ability of fibroblasts to perform unscheduled DNA synthesis (a measure of excision repair) after ultraviolet (UV) irradiation was measured radioautographically for seven species at several times after several UV fluences. Both the initial rate and the maximum incorporation of ['H]dThd increased with the life-span of the species (shrew, mouse, rat, hamster, cow, elephant, and human). Unscheduled DNA synthesis was approximately proportional to the logarithm of life-span.
