Possibilities for the Evolution of the Genetic Code from a Preceding Form

Nature volume 246, pages 22–26 (1973)Cite this article

Abstract

Analysis of the interaction between mRNA codons and tRNA anticodons suggests a model for the evolution of the genetic code. Modification of the nucleic acid following the anticodon is at present essential in both eukaryotes and prokaryotes to ensure fidelity of translation of codons starting with A, and the amino acids which could be coded for before the evolution of the modifying enzymes can be deduced.
