To most of us, DNA stores the code of all living things.
But according to computer scientists, DNA may one day become the preferential storage medium for all things.
This isn’t the first attempt at using the code of life to store digital data, but it’s certainly unique. Here’s the kicker: the system supports random access — selectively reading only a desired file from DNA, rather than the entire database — a first in the field, according to the press release.
Why would we want to store computer data on the fabric of life?
The short answer: breathtaking raw storage capacity and longevity.
The team first translated image and video data into a standard binary code of 0s and 1s. Each image or video is then broken into thousands of pieces. Using a lossless encoding technique called Huffman coding, the team next mapped each piece into short synthetic DNA strands. In this way, a single image may result in thousands of snippets of DNA.
During DNA synthesis, the researchers added a unique identifier — an “address” made up of a short nucleotide sequence — that lets them later reassemble the snippets into a complete image, much like putting together a jigsaw puzzle. To read the data, the DNA is sequenced on a machine, and the nucleotide sequence is translated back into bytes.
