Having found that carbonyl sulfide (COS), works well as a catalyst in the transformation of amino acids to polypeptides, we have now tested COS as a catalyst also for the formation of substances that might be thought of as partners in the building of RNA. The model used was selective energy transfer (SET). This model implies that a certain number of vibrational quanta are donated from the catalyst system and a corresponding number of quanta of the reactant accept the energy thus transferred. In this way, we found that carbonyl sulfide, COS, was a perfect catalyst for combining, first, five molecules of formaldehyde to form one molecule of ribose, and next, five molecules of hydrogen cyanide, HCN, to form one molecule of adenine, one of the nucleobases of RNA. However, beyond this, we found that COS was a perfect catalyst for precisely all reactions, needed to build the RNA, ribonucleic acid.
