Abstract

Abstract: Diversity is an intrinsic feature of life at the species and sequence levels, while the genetic code is a unified feature for cellular and noncellular organisms. How can life display both diversity and unity? In fact, biochemical differences and statistical features of the whole-genome sequences play essential roles in diversification of life. A general method has been proposed to obtain the phylogenetic tree for not only all cellular organisms but also viruses by comparing the distributional features of triplet codons in their genomes. Such a systematic role of the triplet genetic code is beyond its literal meaning during translation.
