    "abstract": "Information theoretic analysis of genetic languages indicates that the\nnaturally occurring 20 amino acids and the triplet genetic code arose by\nduplication of 10 amino acids of class-II and a doublet genetic code having\ncodons NNY and anticodons $\\overleftarrow{\\rm GNN}$. Evidence for this scenario\nis presented based on the properties of aminoacyl-tRNA synthetases, amino acids\nand nucleotide bases.",
