An analysis of the primary sequence of DNA clearly points to the possibility of considering it as a fractal structure, whose fractal properties depend on the species-specific, evolutionary features of the molecule as a whole and the morphological and functional characteristics of its individual elements. Main features of nucleotide distribution of various sizes are described by scenario of evolution, including insertions, deletions, replacements and duplications of DNA segments. The features of the size distribution and spacing of GA, poly-A, CA-, GC-, TA-, TC-, TG-sequences and of Alu elements were investigated. It was found that the repetitive DNA sequence, taking its origin from transposons, is distributed not chaotically in genome, but co-clustered with other types of repetitive elements, genes and genomic components.
