Аннотация: The information capacity of sequences is considered through the calculation of specific entropy of their frequency dictionary. The specific entropy was calculated against the reconstructed dictionary which bears the most probable continuations of shorter strings. The measure developed allows to distinguish the sequences both from the random ones, and those with high level of (rather simple) order. Some applications of the developed methodology to genetics, bioinformatics, and linguistics axe discussed.

Аннотация: New method to reveal the sites in genomes obtaining the high information capacity is developed. A distribution of those sites of the length 3 among 16 viral genomes and I I bacteriophages genomes has been studied. It is shown that some tripletes with high information capacity occur in a family of relatively close genomes with the increased frequency. The molecular evolution aspects of a persistence of highly scored sites with respect to their information capacity among various genomes are discussed.

Аннотация: The information capacity of nucleotide sequences is defined through the calculation of specific entropy of their frequency dictionary. The specific entropy of the frequency dictionary is calculated against the reconstructed dictionary; this latter bears the most probable continuations of the shorter strings. This developed measure allows to distinguish the sequences both from the randons ones, and from those with high level of (rather simple) order. Some implications of the developed methodology in the fields of genetics, bioinformatics, and molecular biology are discussed.
