Information content of the frequency dictionaries, reconstruction, transformation and classification of dictionaries and genetic texts

摘要

A study of the relation between a structure of symbol sequences and the meaning of them encrypted in the interlocation of symbols is a key problem for molecular biology, biophysics and many other fields of sciences. Usually, researchers meet no problem in understating the function of sequences studied. A structure is a much more complicated matter to understand. When studying nucleotide sequences, one often encounters the intron-exon structure, or the structure determined by operons, etc. Further, we should understand the information structure of a nucleotide sequence as its frequency dictionary, either real one, or the reconstructed one, or the transformed one. Such understanding of the structure of a sequence enables a researcher to introduce easily the idea of a closeness of two (or several) structures.
