The researchers claim that the cost of DNA coding is dropping so quickly that within five to 10 years it could be cheaper to store information using this method than in conventional digital devices.

 

Deoxyribonucleic acid or DNA – the chemical that stores genetic instructions in almost all known organisms – has an impressive data capacity. One gram can store up to 455bn gigabytes: the contents of more than 100bn DVDs, making it the ultimate in compact storage media.
