Abstract
Nucleic acid memory strands encoding digital data using a sequence of homopolymer tracts of repeated nucleotides provides a cheaper and faster alternative to conventional digital DNA storage techniques. The use of homopolymer tracts allows for lower fidelity, high throughput sequencing techniques such as nanopore sequencing to read data encoded in the memory strands. Specialized synthesis techniques allow for synthesis of long memory strands capable of encoding large volumes of data despite the reduced data density afforded by homopolymer tracts as compared to conventional single nucleotide sequences.
Claims23
A method of recording data using a nucleic acid memory strand, the method comprising the steps of:
- creating an in silico sequence of bits that represents a dataset;
- synthesizing a nucleic acid memory strand comprising a plurality of homopolymer tracts or heteropolymer tracts having defined compositions, each homopolymer or heteropolymer tract corresponding to a bit of the sequence of bits representing the dataset.
A method of reading data from a nucleic acid memory strand, the method comprising:
- sequencing a nucleic acid memory strand comprising a plurality of homopolymer tracts or heteropolymer tracts having defined compositions;
- converting the nucleic acid memory strand sequence into digitized data, wherein each of the plurality of homopolymer or heteropolymer tracts represents a bit corresponding to a unit of data;
- and
- converting the digitized piece of data to a readable format.
