Comparative statistical analysis of bacteria genomes in "word" context

Statistical analysis of bacteria genomes texts has been performed on the basis of 20 complete genomes origin from Genebank. It has been revealed that the word ranked distributions are quite well approximated by logarithmic law. Results obtained in the absent words investigation show the considerably nonrandom character of DNA texts. In character of autocorrelation function behavior in several genomes period 3 oscillations were found. Short range autocorrelations are present in short ($n=3$) words and practically absent in longer words.

Entropy concepts and DNA investigations

Topological and metric entropies of the DNA sequences from different organisms were calculated. Obtained results were compared each other and with ones of corresponding artificial sequences. For all envisaged DNA sequences there is a maximum of heterogeneity. It falls in the block length interval [5,7]. Maximum distinction between natural and artificial sequences is shifted on 1-3 position from the maximum of heterogeneity to the right as for metric as for topological entropy. This point on the specificity of real DNA sequences in the interval.
