[Synthesis of purine and pyrimidine nucleosides under the action of high temperature and UV-radiation].
By means of UV-spectroscopy, gel filtration, thin layer and paper chromatography, it has been shown that the action of UV irradiation and heat on a dry mixture of nitrogenous bases and deoxyribose results in the formation of nucleoside pool, particulary deoxyadenosine. These energy sources were chosen in order to imitate at least approximately the conditions assumed to exist on the primitive Earth. Similar synthesis takes place in the atmosphere of the three gases studied, being more intensive in CO2 than in N2 or O2.
