DNA repair mechanisms 1 Direct repair A Photo reactivation Ultra violet UV radiations at about 254 nm may cause DNA damage resulting in formation of pyrimidine dimers like TT cytosine dimers may also be formed Enzyme called photolyase can repair such damages by reversing the dimers to normal bases Photolyase can utilize energy from near UVspectrum or blue region about 300 450 nm This is utilized to break the covalent bonds between the dimers and thus
