[An excess of eukaryotic genes is lessened as a result of splicing].

Statistical features of nucleotide sequences are analyzed for the redundancy of their sites, introns vs. exons. In human genes with known exon-intron structure, the introns were found to be more redundant than the exons. The redundancy was defined as the minimal length of a nucleotide sequence not repeated within a gene. Mechanisms alternating exon-intron statistical pattern are discussed.
