When inflexibility is counterproductive: Mechanism of UV-induced DNA Dewar lesion revealed
Excessive exposure to ultraviolet (UV) radiation of sunlight can result in skin damage and may even induce skin cancers. Irradiation with UV light causes mutations in the DNA, which can interfere with or even inhibit the ...
