DNA Fountain enables a robust and efficient storage architecture

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). DNA is the macromolecule that storage all biological information in codes made up of four chemical base, Adenine (A), Guanine (G), Thymine (T), Cytosine (C).Each base is also attached to a sugar molecule and a phosphate molecule.

 Together, a base, sugar, and phosphate are called a nucleotide. These nucleotides form codons that translated into proteins in living cells.  in recent years scientist showed that DNA has the potential to provide large-capacity information storage.  in this study, Erlich and Zielinski present a method called DNA fountain, that is highly robust and approaches the information capacity per nucleotide. using this method they stored 2140000 byte information in DNA oligonucleotide and perfectly retrieved. for more reading refer to reference.
