Intermittency as a universal characteristic of the complete chromosome DNA sequences of eukaryotes: From protozoa to human genomes

TL;DR

This paper investigates the large-scale dynamical properties of eukaryotic chromosome DNA sequences, revealing that they exhibit deterministic chaos and complex structural patterns through models of intermittency and symbolic dynamics.

Contribution

It introduces deterministic models with intermittency and symbolic dynamics to describe large-scale patterns in eukaryotic DNA sequences, highlighting their non-random, chaotic nature.

Findings

DNA sequences exhibit properties of deterministic chaos

Large-scale patterns include segmental duplications and tandem repeats

Gene number balance is non-random

Abstract

Large-scale dynamical properties of complete chromosome DNA sequences of eukaryotes are considered. By the proposed deterministic models with intermittency and symbolic dynamics we describe a wide spectrum of large-scale patterns inherent in these sequences, such as segmental duplications, tandem repeats, and other complex sequence structures. It is shown that the recently discovered gene number balance on the strands is not of random nature, and a complete chromosome DNA sequence exhibits the properties of deterministic chaos.
