[Variations of the length of exons and introns in human genome genes].

The exon-intron organization of genes of all human chromosomes was studied in relation to the density of gene distribution on DNA strands and on the number of introns in genes. The lengths of exons, introns and genes have been found to vary correlatively, and this correlation depends on the density of genes in human chromosomes. It has been established that genes with the exon-intron organization have similar tendencies of variation of the lengths of exons and introns with an increase in the number of introns.
