Splitting of Uracil Dimer by High-energy Electrons

Naturevolume 199page504 (1963) | Download Citation



THYMINE or uracil in frozen aqueous solutions are readily converted into their dimers by ultra-violet irradiation1–3. Using ion exchange chromatography on ‘Dowex 1’, the dimers of both pyrimidines-2-14C were prepared in chromatographic homogeneous forms. Kecently, it was established by us that thymine dimer is easily split into thymine monomer by irradiation with high-energy electrons4.
