On the Problem of Genome Redundancy in Viruses and Prokaryotes

A specific index of nucleotide sequence redundancy, the specific restriction length of a finite frequency dictionary, was determined for a complete set of genes in some viral genomes and a genome of a bacterium, Bacillus subtilis. The distribution of the gene number over the specific restriction length was shown to be bimodal for viral genomes and unimodal for the Bac. subtilis genome. These results agree with earlier data.
