Irradiation of Pyrimidine in Pure H2O Ice with High-Energy Ultraviolet Photons SUMMARY: In Part 3 of pyrimidine beaming, researchers looked at different energy levels of photons and their effect on pyrimidines. They beamed a water and pyrimidine ice mixture with photons of three different wavelengths. Uracil and the molecule that is the precursor to uracil… Continue reading Beaming Pyrimidines Part 3
