Cyclization of nucleotide analogues as an obstacle to polymerization

A R Hill Jr et al. J Mol Evol. 1988.

Abstract

Cyclization of activated nucleotide analogues by intramolecular phosphodiester-bond formation is likely to compete very effectively with template-directed condensation except in the cases of ribo- and arabinonucleotides. This could have excluded derivatives of most sugars from growing polyribonucleotide chains and thus reduced chain-termination in prebiotic polynucleotide synthesis.
