Scientists Turn DNA Into a Virtually Limitless Storehouse
Posted on Aug 17, 2012
The successful translation of a book into genetic coding suggests that the building blocks of life could be used to store data cheaply, durably and with staggeringly little space compared with conventional digital devices.
One gram of artificially synthesized deoxyribonucleic acid—or DNA—stored on a glass chip can hold up to 450 billion gigabytes of information—roughly more than the equivalent of 100 billion DVDs.
DNA’s storage efficiency comes from the fact that it exists in three dimensions. Traditional storage techniques, such as writing on compact discs or hard drives, are confined to two dimensions. Information stored as DNA is also easily copied and maintains its fidelity after thousands of years spent in “non-ideal” conditions, researchers say.
