[0047] See also Figure 1 , which is a schematic diagram of a DNA encoding method provided in one embodiment of the present application. The DNA encoding method provided in an 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 a user may be obtained, or original data such as audio, video, and documents input by a user may be obtained, and the original data may 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 according to a certain number of binary bits, so that the binary data includes several binary data groups. Specifically, the binary data is divided according to 6 binary bits to obtain several 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 only one repeated base (A or T or G or C) at most.

[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 obtained 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 2 repeated bases (AA or TT or GG or GC) at most.

[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 a 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 the embodiment of the present application, the base units corresponding to each binary data group are spliced ​​from small to large according to the number of the binary data group to obtain a base sequence corresponding to the binary data. Among them, since the base unit obtained according to the first mapping table has only one repeated base at most, the GC content is 50%. The base unit obtained according to the first mapping table has only two repeated bases at most, and the GC content is 50%. Therefore, the base sequence obtained by splicing multiple base units also has only two repeated bases at most, and the GC content is also 50%.

[0062] By applying the embodiment of the present application, binary data to be encoded is obtained; the binary data is grouped 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, a preset first mapping table is obtained; according to the preset first mapping table, the binary data group is encoded 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, a preset second mapping table is obtained; according to the preset second mapping table, the binary data group is encoded 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; the base units corresponding to each binary data group are merged 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, encodes the binary data group into corresponding base units, and the GC content of the base sequence after the base units are merged strictly meets the GC balance requirement, and the GC content is 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 executor of the DNA encoding method can be a DNA encoding device, and the DNA encoding device includes but is not limited to a computer, a tablet, a mobile phone, etc.

[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 a 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 with a length of 5, and the right side is a base unit with a length of 4.

[0078] Since the 4 bases of each base unit in the first mapping table only contain 2 CCs or 2 GGs or 1 C and 1 G, the GC content in each base unit is 50%, which meets the GC balance requirement. In addition, since {A, T} and {G, C} appear alternately in the 4 bases of each base unit, there is only one repeated base in each base unit at most, and there will be no continuous AA or TT or CC or GG, which avoids the appearance of long repeated bases and improves the accuracy of subsequent DNA molecule synthesis and sequencing.

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

[0080] S401: constructing a second mapping table according to a second mapping relationship between the binary sequence and the 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 with a length of 5, and the right side is a base unit with a length of 4.

[0087] Since the 4 bases of each base unit in the second mapping table only contain 2 CCs or 2 GGs or 1 C and 1 G, the GC content in each base unit is 50%, which meets the GC balance requirement. In addition, since {A, T} and {A, T} appear adjacent to each other, or {G, C} and {G, C} appear adjacent to each other in the 4 bases of each base unit, there are at most 2 repeated bases in each base unit, which avoids the appearance of long repeated bases and improves 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 and T pairing, and G and C pairing.

[0091] In the embodiment 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 an embodiment of the present application comprises the following steps:

[0094] S100: Obtaining 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 DNA molecules generated by the DNA encoding method can be sequenced by DNA sequencing technology to obtain the base sequence. The base sequence generated by the DNA encoding method can also be directly obtained.

[0097] S200: Divide the base sequence into a plurality of base units.

[0098] In the embodiment of the present application, the base sequence can be divided into a group 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 position of the base unit in the base sequence, and the numbers are 1, 2, 3, ..., N. For example, the base units corresponding to the base sequence "TCTCGTCATCCT...CTAC...CAGT" are: 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 of the aforementioned steps S30 and S40, and are not described again herein.

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

[0102] In the 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 consistent base unit is matched, the binary sequence corresponding to the base unit is obtained. The binary sequence includes 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 the 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, which 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, and a binary bit 1 is added before the first binary bit of the binary sequence to obtain 6 binary bits, which 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: merging the binary data groups corresponding to each base unit to obtain binary data corresponding to the base sequence.

[0107] In the embodiment of the present application, the binary data group corresponding to each base unit is spliced ​​from small to large according to the 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.
