INTRONS DIFFER FROM EXONS BY THEIR REDUND ANCY

This paper is devoted to an analysis of the intrinsic structure of the gene from the point of view of the redundancy of different structural units - exons and introns. Human genes for which the exon-intron stru cture has - been clearly established were Studied. The redundancy of e ach exon and intron in the gene was determined. It was shown that, in human genes, introns are more redundant than exons. Redundancy is dete rmined as the smallest length of a word (oligonucleotide) beginning wi th which all words in the studied nucleotide sequence are found exactl y once. Mechanisms leading to the disruption of the general pattern of ratios of redundancy of exons and introns are studied.
