The Atmosphere of the Primitive Earth and the Prebiotic Synthesis of Amino Acidsiscussed by Urey. This atmosphere would have contained CH., N. with traces of NH., water and hydrogen. Only traces of NH. would have been present because of its solubility in water. UV light and electric discharges were the major sources of energy for amino acid synthesis, with electric discharges b

The Prebiotic Synthesis of Oligonucleotidescation in solution. It also presents preliminary results from this laboratory on the prebiotic synthesis of thymidine oligodeoxynucleotides. A discussion, based on the physicochemical properties of RNA and DNA oligomers, relevant to the molecular evolution of these compounds leads to the tentative h
