Abstract: The inventions fall into the category of means of coding/ decoding of all types of information (text file, images, sound files) using DNA, RNA and amino acid sequences. A coding method was suggested according to which a data array to be coded is divided into chunks, each of which is assigned at least one element of the molecular genetic system; the set of elements in the system is supplemented by relevant indexing information consisting of i data bits and k check bits. Each piece of i+k bit data shall be written as a multiplet of the molecular genetic system consisting of the n number of nitrogenous bases or corresponding amino acids. Besides the information to be coded, one shall also write the value n and the information about the selected method of transforming the matrix into a sequence and the reading order. A decoding method was suggested according to which the machine-readable sequence is divided into chunks of information to be decoded, which includes combinations of i data bits and k check bits, and assigned at least one multiplet of the molecular genetic system consisting of the n number of nitrogenous bases or corresponding amino acids. The molecular genetic system used for the coding/ decoding consists of a base representing a four-nitrogenous base matrix A TU ; the nitrogenous bases are grouped according to the number of hydrogen bonds and the number of condensed rings contained in the molecular structures of nitrogenous bases; the matrix is formed in advance by raising tensors of each previous generation matrix to the second power multiple times in order to obtain a next-generation matrix. The system binary indices that form the i data bits correspond to the selected characteristic of the nitrogenous bases. As a result, the effectiveness of antinoise coding and decoding is enhanced due to the increase in the volume of transmitted and received information and due to the decrease in the number of elements used for coding/ decoding. 2 independent claims, 33 dependent claims, 17 illustrations.
