A technique for the study of correlations in segmented DNA sequences is developed. Within this approach the effects of compositional patchiness are separated from the beginning, allowing us to display the refined effects of structural coupling between different segments.

โฆ Synopsis
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.

Correlation functions in large sets of non-homologous protein sequences are analysed. Finite size corrections are applied and fluctuations are estimated. As symbol sequences have to be mapped to sequences of numbers to calculate correlation functions, several property codes are tested as such mappin
The hidden periodicities in various genomes can be identified via a Fourier transform of genomic DNA sequences. The typical search strategies are described and the corresponding statistical criteria are presented. The methods are applied to the structural analysis of genome for bacteriophage PHIX174
