Knighting in sequence biology Edward N. Trifonov Genome classification, construction of phylogenetic trees, became today a major approach in studying evolutionary relatedness of various species in their vast - versity. Although the modern genome clustering delivers the trees which are very similar to those generated by classical means, and basic terminology is the same, the phenotypic traits and habitats are not anymore the playground for the classi- cation. The sequence space is the playground now. The phenotypic traits are - placed by sequence characteristics, "words," in particular....

Length of introns varies from tens to tens of thousands nucleotides. The wide variety of lengths of introns and exons in genomes may be caused by evolutionary factors. To reveal these factors we applied a few techniques of factor analysis. The exon-intron structures of eukaryotes genes are quite different from each other, and studying of the evolution of such structures has no obvious attitude. Our choice was to perform statistical analysis of certain average characteristics of these structures. Comparing those chromosomal and genomic averages, we have selected an appropriate technique of...
