Abstract
Polynucleotides were found to suppress the dimerization reaction of aqueous glycine with trimetaphosphate as the condensing agent. Small anions (chloride, acetate, and phosphate) did not show this effect. The reaction was studied at a pH of about 11.5 and at 70 degrees C and room temperature with a 13 mM concentration of glycine and trimetaphosphate. Under these conditions, the effect of the polynucleotides was in the following order: polyguanylic acid less than polycytidylic acid less than polyadenylic acid less than polyuridylic acid. The result may have a significant implication for the understanding of processes of chemical evolution.
