Revelation and Classification of Dinucleotide Periodicity of Bacterial Genomes Using the Method of Information Decomposition

We have applied information decomposition to show the presence of many sequences in prokaryotic genomes that possess latent dinucleotide periodicity but have not been found before. More than two hundred DNA sequences having such a latent periodicity were found. These sequences belonged to the 94 different microbial genomes. The classification made has shown that all of the sequences could be assigned to the 45 classes according to the type of latent dinucleotide period. A probable functional and evolutional meaning of the latent dinucleotide periodicity in different prokaryotic genomes is discussed.
