Abstract
We present a method for unified statistical analysis of short and
long range correlations between various nucleotides in genomic DNA
strands. The approach is based on the mutual study of Fourier structure
factor spectra and pair correlation functions. The analysis of cross
correlations in the different ranges of structural spectra permits
identification of the main sources of correlations, namely, the
coherent point mutations, coincident periodicities or large scale
density variations. The technique for assessment of structural
coupling between various genes in the genome is also described.
