[Redundancy of genetic sequences and mosaic structure of a genome]

A new method is developed to measure and compare the redundancy of genes. The method is based on the creating a Frequency/Correlation Dictionary of a gene. The Dictionary is a set of all possible words (i.e., subsequences) which could be met within a gene, of a length from 1 to N, where N is the length of the gene. The measure of redundancy of a gene is the minimal length of words which occur in the gene as a single copy. The results of the redundancy measurements are presented in the paper. It is shown that genes are not homogeneous in respect of redundancy of various sites in the gene. This phenomenon was called a mosaic pattern.
