[Changes of introns and exons length in genes of arabidopsis, rice, nematode and human].

ABSTRACT

Genes of Arabidopsis thaliana, Orysa sativa, Caenorhabditis elegans, Homo sapiens have been studied by computer analysis. The average intron and exon lengths in genes of these organisms decreases with increase of intron number in genes. The length of introns and exons in A. thaliana and O. sativa genes is change with increase of intron number in genes by high coefficient of correlation. Linear dependence between the sum of exon lengths and intron number in genes increased proportionally to number of gene introns. The average length of introns and genes of human depend on density of genes in DNA.
