Abstract

There are many biological mechanisms which introduce long-range correlations into the DNA molecule. One of the most important is replication of chromosomes, its mechanisms and topology. Replication associated mutational pressure, defined as specific preferences in nucleotide substitutions during replication, generates asymmetry in the genome. On the other hand, substitution rates, which determine the evolutionary turnover time of a nucleotide, are highly correlated with the fraction of that nucleotide in the genome. Assuming the Azbel hypothesis that the number of mutations per genome per generation is invariant and universal, a general rule for mutational pressure can be formulated: the half-time of a nucleotide turnover in the genome is linearly dependent on the number of this nucleotide in the genome.
