Chemical etiology of nucleic acid structure

A Eschenmoser. Science. .

Abstract

Systematic chemical studies indicate that the capability of Watson-Crick base-pairing is widespread among potentially natural nucleic acid alternatives taken from RNA's close structural neighborhood. A comparison of RNA and such alternatives with regard to chemical properties that are fundamental to the biological function of RNA provides chemical facts that may contain clues to RNA's origin.
