WebThe enzyme photolyase consists of FAD (flavin adenine dinucleotide) and MTHF (methylene tetra hydro folate) cofactors. Firstly, the MTHF absorbs visible light of a higher wavelength (Mostly 384nm) to repair the DNA damage. After absorbing the energy coming from the visible light, MTHF gets excited. WebDNA Repair: Photolyase results of prior research Skin cancer is the most common form of cancer in the United States and can be lethal if not properly treated. The leading cause of skin cancer is epidermal absorption of ultraviolet (UV) radiation. DNA is believed to be the primary chromophore.
