Initial amino acid:codon assignments and strength of codon:anticodon binding

The paper investigates codon:anticodon binding strengths and suggests that family box codons may have been used in early peptide synthesis due to tighter binding and simultaneous codon recognition.

Potentially prebiotic synthesis of aminoacyl-RNA via a bridging phosphoramidate-ester intermediate

This paper describes a prebiotically plausible mechanism for aminoacyl-RNA synthesis using phosphoramidate-ester intermediates and mild acid hydrolysis.
