[0047] See also Figure 1 , which is a flow chart of a DNA encoding method provided in one embodiment of the present application. The DNA encoding method provided in the embodiment of the present application comprises the following steps:

[0048] S10: Obtain binary data to be encoded.

[0049] Among them, binary data is the underlying representation of files on a computer, consisting of 0 and 1. Any file stored on a computer has unique binary data.

[0050] In an embodiment of the present application, binary data input by the user can be obtained, and original data such as audio, video, and documents input by the user can also be obtained, and the original data can be converted into binary data.

[0051] S20: Grouping the binary data to obtain a plurality of binary data groups; wherein each binary data group includes 6 binary bits.

[0052] In an embodiment of the present application, the binary data is divided into a group of a certain number of binary bits, so that the binary data includes a plurality of binary data groups. Specifically, the binary data is divided into a group of 6 binary bits to obtain a plurality of binary data groups. Each binary data group can be numbered according to the order of the position of the binary data group in the binary data, and the numbers are 1, 2, 3, ..., N. For example, the binary data "001010011100101001 ... 110100 ... 010011" corresponds to the binary data groups: 001010 (number 1), 011100 (number 2), 101001 (number 3), ..., 110100 (number i), ..., 010011 (number N).

[0053] S30: For each binary data group, when the first binary bit of the binary data group is 0, obtain a preset first mapping table; according to the preset first mapping table, encode the binary data group into corresponding base units; the first mapping table includes a first mapping relationship between a binary sequence from the second binary bit to the sixth binary bit in the binary data group and the base unit.

[0054] The base unit includes several bases, and there are four types of bases: guanine (G), cytosine (C), adenine (A) and thymine (T).

[0055] In the preset first mapping table, a binary sequence corresponds to a unique base unit. The binary sequence includes 5 binary bits. The GC content of each base unit in the preset first mapping table is 50%, and there is at most one repeated base (A, T, G, or C).

[0056] In an embodiment of the present application, when encoding a binary data group, the first binary bit of the binary data group is first identified. When the first binary bit of the binary data group is 0, the base unit corresponding to the binary sequence from the second binary bit to the sixth binary bit of the binary data group is searched from a preset first mapping table.

[0057] S40: When the first binary bit of the binary data group is 1, obtain a preset second mapping table; according to the preset second mapping table, encode the binary data group into corresponding base units; the second mapping table includes a second mapping relationship between the binary sequence from the second binary bit to the sixth binary bit in the binary data group and the base unit.

[0058] In the preset second mapping table, a binary sequence corresponds to a unique base unit. The binary sequence includes 5 binary bits. The GC content of each base unit in the preset second mapping table is 50%, and there are only two repeated bases (AA or TT or GG or GC).

[0059] In an embodiment of the present application, when encoding a binary data group, the first binary bit of the binary data group is first identified. When the first binary bit of the binary data group is 1, the base unit corresponding to the binary sequence from the second binary bit to the sixth binary bit of the binary data group is obtained from the preset second mapping table.

[0060] S50: Merge the base units corresponding to each binary data group to obtain a base sequence corresponding to the binary data.

[0061] In this embodiment of the present application, the base units corresponding to each binary data group are spliced ​​together according to the binary data group numbering from smallest to largest to obtain a base sequence corresponding to the binary data. Since the base units obtained according to the first mapping table have at most only one repeated base, their GC content is 50%. The base units obtained according to the first mapping table have at most only two repeated bases, their GC content is 50%. Therefore, the base sequence obtained by splicing multiple base units also has at most only two repeated bases, and their GC content is also 50%.

[0062] An embodiment of the present application is applied, by obtaining binary data to be encoded; grouping the binary data to obtain several binary data groups; wherein each binary data group includes 6 binary bits; for each binary data group, when the first binary bit of the binary data group is 0, obtaining a preset first mapping table; according to the preset first mapping table, encoding the binary data group into corresponding base units; the first mapping table includes a first mapping relationship between a binary sequence from the second binary bit to the sixth binary bit in the binary data group and the base unit; when the first binary bit of the binary data group is 1, obtaining a preset second mapping table; according to the preset second mapping table, encoding the binary data group into corresponding base units; the second mapping table includes a second mapping relationship between a binary sequence from the second binary bit to the sixth binary bit in the binary data group and the base unit; merging the base units corresponding to each binary data group to obtain a base sequence corresponding to the binary data. The present application groups the binary data to be encoded, selects the corresponding mapping table according to the value of the first binary bit of the binary data group, and encodes the binary data group into corresponding base units. The GC content of the base sequence after the base units are merged strictly meets the GC balance requirement, with a GC content of 50%. At the same time, the maximum length of the same continuous base subsequence in the base sequence is only 2 bases, avoiding the influence of long repeated bases in the base sequence and the extreme GC content in the base sequence during DNA synthesis and sequencing, thereby improving the accuracy of the base sequence during DNA synthesis and sequencing.

[0063] In an optional embodiment, step S10 includes steps S101 to S102, which are specifically as follows:

[0064] S101: Obtain original data to be encoded.

[0065] Among them, the execution subject of the DNA encoding method can be a DNA encoding device, which includes but is not limited to computers, tablets, and mobile phones.

[0066] In the embodiment of the present application, the original data to be encoded includes but is not limited to files, photos, and audio and video data.

[0067] S102: Convert the original data into binary data.

[0068] In the embodiment of the present application, the original data is stored as electronic data in a digitized form to obtain data in a binary format.

[0069] By converting the original data into a binary format, the binary data to be encoded can be obtained automatically and quickly.

[0070] In an optional embodiment, the step of obtaining the preset first mapping table in step S30 includes step S301, which is specifically as follows:

[0071] S301: Constructing a first mapping table according to a first mapping relationship between a binary sequence and a base unit; wherein the binary sequence includes 5 binary bits, the base unit includes 4 bases, and adenine and thymine are spaced apart from each other, or guanine and cytosine are spaced apart from each other in the 4 bases.

[0072] In the embodiment of the present application, the specific form of the first mapping relationship between the binary sequence and the base unit is as follows:

[0073] 00000<-->ACAC, 00001<-->ACAG, 00010<-->ACTC, 00011<-->ACTG, 00100<-->AGAC, 00101<-->AGAG, 00110<-->AGTC, 00111<-->AGTG;

[0074] 01000<-->TCAC, 01001<-->TCAG, 01010<-->TCTC, 01011<-->TCTG, 01100<-->TGAC, 01101<-->TGAG, 01110<-->TGTC, 01111<-->TGTG;

[0075] 10000<-->GACA, 10001<-->GACT, 10010<-->GAGA, 10011<-->GAGT, 10100<-->GTCA, 10101<-->GTCT, 10110<-->GTGA, 10111<-->GTGT;

[0076] 11000<-->CACA, 11001<-->CACT, 11010<-->CAGA, 11011<-->CAGT, 11100<-->CTCA, 11101<-->CTCT, 11110<-->CTGA, 11111<-->CTGT.

[0077] Among them, <--> is a mapping symbol, the left side of the symbol is a binary sequence of length 5, and the right side is a base unit of length 4.

[0078] Because the four bases in each base unit in the first mapping table only contain two CCs, two GGs, or one C and one G, the GC content in each base unit is 50%, meeting the GC balance requirement. Furthermore, because {A, T} and {G, C} alternate within the four bases in each base unit, each base unit contains at most one repeated base, with no consecutive AA, TT, CC, or GG sequences. This prevents long base repeats and improves the accuracy of subsequent DNA synthesis and sequencing.

[0079] In an optional embodiment, the step of obtaining the preset second mapping table in step S40 includes step S401, which is specifically as follows:

[0080] S401: Construct a second mapping table based on a second mapping relationship between a binary sequence and a base unit; wherein the binary sequence includes 5 binary bits, the base unit includes 4 bases, and in the 4 bases, adenine and thymine are adjacent, and guanine and cytosine are located on both sides, or guanine and cytosine are adjacent, and adenine and thymine are located on both sides.

[0081] In the embodiment of the present application, the specific form of the second mapping relationship between the binary sequence and the base unit is as follows:

[0082] 00000<-->ACCA, 00001<-->ACCT, 00010<-->ACGA, 00011<-->ACGT, 00100<-->AGCA, 00101<-->AGCT, 00110<-->AGGA, 00111<-->AGGT;

[0083] 01000<-->TCCA, 01001<-->TCCT, 01010<-->TCGA, 01011<-->TCGT, 01100<-->TGCA, 01101<-->TGCT, 01110<-->TGGA, 01111<-->TGGT;

[0084] 10000<-->GAAC, 10001<-->GAAG, 10010<-->GATC, 10011<-->GATG, 10100<-->GTAC, 10101<-->GTAG, 10110<-->GTTC, 10111<-->GTTG;

[0085] 11000<-->CAAC, 11001<-->CAAG, 11010<-->CATC, 11011<-->CATG, 11100<-->CTAC, 11101<-->CTAG, 11110<-->CTTC, 11111<-->CTTG.

[0086] Among them, <--> is a mapping symbol, the left side of the symbol is a binary sequence of length 5, and the right side is a base unit of length 4.

[0087] Because each base unit in the second mapping table contains only two CCs, two GGs, or one C and one G, the GC content of each base unit is 50%, meeting the GC balance requirement. Furthermore, because each base unit contains either {A, T} and {A, T} adjacent to each other, or {G, C} and {G, C} adjacent to each other, each base unit contains at most two repeated bases, avoiding the occurrence of long base repeats and improving the accuracy of subsequent DNA molecule synthesis and sequencing.

[0088] In an optional embodiment, after step S50, step S501 is included, which is specifically as follows:

[0089] S501: Using DNA synthesis technology, the base sequence is synthesized into a DNA molecule.

[0090] Among them, DNA synthesis technology refers to a method of artificially connecting deoxynucleotides one by one to synthesize DNA chains based on the principle of complementary base pairing of DNA, that is, A pairs with T and G pairs with C.

[0091] In the embodiments of the present application, after the base sequence is obtained, the base sequence can be synthesized into a DNA molecule through DNA synthesis technology to facilitate subsequent DNA sequencing.

[0092] By synthesizing base sequences into DNA molecules, encoded binary data storage can be achieved, saving data storage space.

[0093] See also Figure 2 , which is a flow chart of a DNA decoding method provided in one embodiment of the present application. The DNA decoding method provided in the embodiment of the present application comprises the following steps:

[0094] S100: Acquire a base sequence generated according to the above-mentioned DNA encoding method.

[0095] The execution subject of the DNA decoding method may be a DNA decoding device, which includes but is not limited to a computer, a tablet, a mobile phone, etc.

[0096] In the embodiments of the present application, the base sequence can be obtained by sequencing the DNA molecules generated by the DNA encoding method using DNA sequencing technology, or the base sequence generated by the DNA encoding method can be directly obtained.

[0097] S200: Divide the base sequence into several base units.

[0098] In an embodiment of the present application, the base sequence can be divided into groups of a certain number of bases to obtain a number of base units. Specifically, the base sequence can be divided into groups of 4 bases to obtain a number of base units, and each base unit is numbered according to the order of the base unit's position in the base sequence, and the numbers are 1, 2, 3, ..., N. For example, the base sequence "TCTCGTCATCCT...CTAC...CAGT" corresponds to the base units: TCTC (number 1), GTCA (number 2), TCCT (number 3), ..., CTAC (number i), ..., CAGT (number N).

[0099] S300: For each base unit, obtain a preset mapping table; wherein the preset mapping table includes a first mapping table and a second mapping table.

[0100] In the embodiment of the present application, the first mapping table and the second mapping table are consistent with the mapping tables in the aforementioned steps S30 and S40, and are not described again here.

[0101] S400: Decode each base unit into a corresponding binary sequence according to the first mapping table and the second mapping table.

[0102] In this embodiment of the present application, each base unit is matched with the base units in the first mapping table and the second mapping table. If a matching base unit is found, the binary sequence corresponding to the base unit is obtained. The binary sequence consists of 5 binary bits. For example, the binary sequence corresponding to the base unit "TCTC" is "01010", and the binary sequence corresponding to the base unit "TCCT" is "01001".

[0103] S500: For the binary sequence corresponding to each base unit, when the binary sequence is in the first mapping table, add binary bit 0 before the first binary bit in the binary sequence to obtain the binary data group corresponding to the base unit; when the binary sequence is in the second mapping table, add binary bit 1 before the first binary bit in the binary sequence to obtain the binary data group corresponding to the base unit.

[0104] In this embodiment of the present application, when the base unit to be decoded is the same as a base unit in the first mapping table, the binary sequence corresponding to the base unit to be decoded is found in the first mapping table, and a binary bit 0 is added before the first binary bit of the binary sequence to obtain 6 binary bits. These 6 binary bits are used as the binary data group after decoding the base unit to be decoded. For example, the binary data group corresponding to the base unit "TCTC" is "001010".

[0105] When the base unit to be decoded is the same as a base unit in the second mapping table, the binary sequence corresponding to the base unit to be decoded is found in the second mapping table. The binary bit 1 is added before the first binary bit of the binary sequence to obtain 6 binary bits. These 6 binary bits are used as the binary data group after decoding the base unit to be decoded. For example, the binary data group corresponding to the base unit "TCCT" is "101001".

[0106] S600: Merge the binary data groups corresponding to each base unit to obtain binary data corresponding to the base sequence.

[0107] In this embodiment, the binary data groups corresponding to each base unit are concatenated in ascending order of base unit number to obtain the binary data corresponding to the base sequence. For example, the base sequence "TCTCGTCATCCT...CTAC...CAGT" corresponds to the binary data "001010011100101001...110100...010011".

[0108] The above-mentioned DNA decoding method corresponds to the aforementioned DNA encoding method, and can decode the base sequence generated by the DNA encoding method and restore it to binary data, thereby realizing the reading of binary data.
