[Abiogenic nucleoside synthesis in the presence of phosphorus salts].

By means of UV-spectroscopy, gel-filtration, ion-exchange and thin layer chromatography it has been shown that the action of ionizing radiation on the mixture of dry preparations of adenine and deoxyribose in the presence of the K, Na and Ca phosphates results in the formation of nucleoside-like substances. The phosphates catalyze or inhibit the nucleoside synthesis but they are not phosphorylating agents. The data obtained indicate the reality of abiogenic synthesis of nucleoside-like substances from the mixture of dry preparations of adenine and deoxyribose in the lithosphere during chemical evolution.
