abstract：:Eukaryotic cells irradiated with high doses of UV exhibit cell-cycle responses referred to as G(1)/S, intraS, and G(2)/M checkpoints. After a moderate UV dose that approximates sunlight exposure and is lethal to fission yeast checkpoint mutants, we found unexpectedly that these cell-cycle responses do not occur. Inste...
