Embodiment Construction

[0022] In order to further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings and specific embodiments.

[0023] figure 1 It is a step diagram of the method for storing character lattices in DNA character codes of the present invention. In the method, each character or character in the font library is represented by a DNA sequence of 8-10 bases, and the generated character code is N+1. , such as the first 9 DNA base sequences of the 10-digit character code are randomly generated, and the last 1 digit is based on the check code generated by the first 9 digits to verify whether there is an error in the 9-digit character code.

[0024] Through the check code, it can be judged whether a gene mutation has occurred during the DNA storage process, resulting in a change in the character code. Generally speaking, during the DNA replication process, the probability of a base error is less than ...

Abstract

The invention discloses a method for storing a character dot matrix by using a DNA character code. The method comprises the following steps of: expressing characters or character dot matrixes by usinga DNA character code with the length of N basic groups, wherein the character code is in the form of N + 1, the last bit of the character code is a check code obtained through statistical calculationaccording to the previous N basic groups, the obtained character code is added to the beginning and the end of the corresponding character or character dot matrix and added to the dictionary, and character dot matrix storage is directly carried out by using the character code with the check code generated by the method; by the adoption of the character dot matrix storage method, the defect that acharacter dot matrix DNA storage method is prone to generating large-segment repeated DNA sequences can be overcome, meanwhile, the short-length DNA character codes are adopted to replace character dot matrixes to record character information, and the storage density is greatly improved.

Description

technical field [0001] The invention discloses a method for storing character lattices using DNA character codes, belonging to the fields of biotechnology and information technology. Background technique [0002] DNA is an important carrier of genetic material, a linear or circular double-helix biomacromolecule produced by natural organisms through billions of years of evolution. In the 1950s, DNA was confirmed by scientists as the genetic information carrier of organisms. Compared with ordinary information storage carriers, DNA has its unique natural advantages in data storage: high storage density, 1 gram of DNA can save the world's All book content; stable and long-term storage, which can reach tens of thousands of years to millions of years; easy to carry, can be carried by bacteria or living organisms or placed in containers for long-term storage, etc. [0003] In traditional storage media, paper is mainly represented by graphics and characters, and information carrier...
