Vestiges of early molecular processes leading to the genetic code.
We compare predictions from a proposed model for the origin of the genetic code (J. Theor. Biol (1993) 164, 291-305) with existing information on the base content of codons and abundance of amino acid in different organisms. A comparison is also made between the three groups of amino acids suggested by the model and the two classes of aminoacetyl-tRNA synthetases. The observed agreements tend to support the model.
