Claims15
A storage method of DNA digital data, the method comprising:
- encoding a plurality of bit data to a plurality of base sequences including at least one degenerate base;
- and
- synthesizing at least two types of bases constituting the at least one degenerate base on a substrate based on a mixing ratio.
Device for storing data in DNA in which a plurality of base sequences to which a plurality of bit data is encoded is divided and stored as a basic storage unit, the device comprising:
- molecules in which a plurality of bases is synthesized based on a base sequence corresponding to the basic storage unit among the plurality of base sequences,
- wherein the base sequence includes a first degenerate base consisting of at least two types of bases, and
- the molecules include
- first molecules in which a base is synthesized among the at least two types of bases, and
- second molecules in which at least another base is synthesized among the at least two types of bases.
A decoding method of DNA data, comprising:
- categorizing a plurality of DNA fragments according to an address;
- analyzing a base at the same position with respect to each of the plurality of categorized DNA fragments;
- calculating a scatter plot of a base ratio based on a result of the analysis;
- determining a base at a corresponding location as a degenerate base when the scatter plot of the base ratio is a mixing ratio of at least two bases;
- and
- decoding data based on the determined degenerated base.
