In the abstract, the number 160 is incorrect due to a logical flaw in its calculation. The number 160 should be replaced with "many". In addition, the Results section, the second and third paragraphs under the subheading "Example 2" contain a logical flaw. Please consider the following alternate text: In short, each point mutation inside a pure GA-sequence would split it into 2 smaller GA-sequences. As a result, one may conclude that pure GA-sequences are conspicuously protected from point mutations based on the following argument. My previous study of point mutations in vertebrate genomes  suggested that their incidence is proportional to the length of a DNA sequence at a rate of 3.3 point mutations/[Kb]. Thus, the long GA-sequences should become more likely fragmented by point mutations than the short ones. (In quantitative terms, the number of GA-sequences of size L should decay exponentially with increasing numbers M of mutations (Exponent = - r L M )). In contrast, the Pareto-distribution of the sizes of pure GA-sequences (eq. 1 and Fig. 2), is characterized by a conspicuous presence of many, very long sequences. Clearly, many million years of evolution failed to fragment these sequences into many small ones.
