Exposure to ultraviolet (UV) radiation can cause the formation of thymine dimers, where two adjacent thymine bases become covalently linked. This dimerization can lead to DNA damage and mutations if ...

UV light has a short wavelength (~10 to 400 nm). UV has a lethal effect on most organisms primarily because of its ability to cause the formation of thymine dimers in DNA. Thymine dimers are two ...

Spectroscopic 6 and structural 7 data show that base flipping occurs when the helicase-like enzyme UvrB scans DNA for thymine dimers and other bulky lesions. Whereas undamaged DNA can flip out ...

Both can decrease erythema and the formation of thymine dimers when taken orally in combination (Fuchs & Kern, 1998; Placzek et al., 2005). However, consuming either one alone does not offer the ...
