Abstract

The invention relates to the technical field of biological information, and provides a coding and decoding method from binary information to a base sequence for DNA data storage and a processing device. The method comprises the following steps: Constructing a mapping coding rule base of the reference base group-reference binary unit by using the reference base group to represent the reference binary unit; acquiring binary data to be coded, wherein the binary data comprises a plurality of binary units; and coding the plurality of binary units by adopting N different mapping encoding rules to obtain a base sequence corresponding to the binary data. According to the coding and decoding method from the binary information to the base sequence for DNA data storage provided by the invention, theproblems of single base repetition and non-uniform GC in the base sequence can be selectively prevented, so that the synthesizability and sequencing convenience of the base sequence are improved; andmore possibilities are provided for encryption and secure storage of the data.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular to a method and device for encoding and decoding binary information into base sequences for DNA data storage. Background technique [0002] The rapid development of the Internet and big data and other fields has prompted the explosive growth of information in today's society. Traditional storage media, including hard disks, magnetic tapes, and optical discs, are far from being able to meet the needs of future large-scale data storage due to their short storage life, high maintenance costs, and low storage density. Deoxyribose nucleic acid (DeoxyriboNucleic Acid, DNA), as an information storage medium developed in recent years, has the advantages of high storage density, long storage time, and low maintenance cost, and is considered to be one of the most potential mediums for future information storage. [0003] DNA molecules have four bases, which are: adenine (A...
