Embodiment Construction

[0026] The following will take the writing target information "DNA storage" as an example to further describe in detail the method and system for parallel addressing and writing of DNA information storage according to the present invention.

[0027] Such as figure 1 As shown, the parallel addressing and writing method for DNA information storage in this embodiment includes:

[0028] 1) convert target information into binary code;

[0029] 2) According to the data storage micro-pool layout rules on the DNA information storage medium, encode the converted binary code into the corresponding DNA coding strand combination, and select the corresponding DNA coding strand library from the pre-prepared DNA coding strand library according to the DNA coding strand combination. chain, preparing a DNA coding strand mixed solution comprising all selected DNA coding strands; all DNA coding strands in the DNA coding strand library have an address adaptation region as an address adapter at on...

Abstract

The invention discloses a DNA information storage parallel addressing write-in method and system. The method comprises the steps of: converting target information into a binary code; coding the binary code into a corresponding DNA coding chain combination according to a data storage micro-pool arrangement rule on a DNA information storage medium; selecting a corresponding DNA coding chain from a DNA coding chain library to prepare a DNA coding chain mixed solution; covering the DNA coding chain mixed solution on the DNA information storage medium; enabling the DNA coding chain to perform hybridization reaction with a DNA address chain which is complementarily paired in the corresponding data storage micro-pool; and finally closing and washing the data storage micro-pool to complete the writing of target information. According to the method and system, DNA long-chain synthesis is not needed, a DNA short-chain combination encoded with information and the address chain are subjected to the rapid hybridization reaction, high parallelism of DNA information storage and write-in functions is achieved, and natural advantages of a biological system can be brought into full play.

Description

technical field [0001] The invention belongs to DNA storage technology, in particular to a DNA information storage parallel addressing and writing method and system. Background technique [0002] DNA storage technology is a new application of biotechnology in the field of information storage. DNA has the advantages of long storage time, large storage information capacity, and strong environmental adaptability. It is an ideal medium for digital information storage. A typical information storage technology based on DNA synthesis and sequencing uses the base as the information coding unit to establish a one-to-one correspondence between the sequence information of the base site and the binary information, which has the advantages of strong resistance to electromagnetic shock and high data density . Although this scheme has a large amount of information storage, there are problems such as long reading and writing time and poor parallelism, which restrict the practical applicati...
