DNA-based storage scheme could be scaled far beyond current worldwide information volumes.

DNA-based storage scheme could be scaled far beyond current worldwide information volumes.

In an  article  entitled, “Towards practical, high-capacity, low-maintenance information storage in synthesized DNA,”  published online 23rdJanuary issue of Nature,  Nick Goldman and six of his associates affiliated to European Bioinformatics Institute, UK  and Agilent Technologies, Genomics– LSSU, USA have described  DNA as a powerful device for the digital production, transmission and storage because of its capacity for high-density information encoding,  b) longevity under easily achievable  conditions and c) proven track record as an information carrier.

Unlike its initial capacity when  this device could encode only trivial amounts of information, the current technology can reliably store more information than has hitherto been possible.  The authors have succeeded in encoding computer files of 739 kilobytes of hard-disk storage into a DNA code, synthesized this volume of DNA, sequenced it and reconstructed the original files with 100% accuracy. According to these authors their DNA-based storage scheme could be scaled far beyond current worldwide information volumes. The latest technology developed by them can be used  for large-scale, long-term and infrequently accessed digital archiving.
