    "abstract": "The evolution in coding DNA sequences brings new flexibility and freedom to\nthe codon words, even as the underlying nucleotides get significantly ordered.\nThese curious contra-rules of gene organisation are observed from the\ndistribution of words and the second moments of the nucleotide letters. These\nstatistical data give us the physics behind the classification of bacteria.",
