Abstract
By performing several statistical tests, we confirm that long-range
correlation exist and are typical for long eukaryotic DNA sequences.
Different types of "critical exponents" for characterization of
DNA fractality are discussed. As to possible explanation of the
phenomenon, our computer simulations indicate that simple mosaic
structure of genome, without correlations between blocks, cannot
be solely accounted for the observed statistical properties of
DNA texts. We propose the concept of "fractal patchiness",
which fully explains statistical observations, and shed light on the
possible origin of long-range correlations in DNA sequences.
