Nowadays, we have seen many companies running in a race for building their data centers to store all the business transactions, pictures, videos and messages uploaded by their users. In recent research, it has been found that the storage of digital data can be cut down to the size of a sugar cube.
Strauss, a Microsoft Researcher in Redmond, Washington along with other scientists have come up with an idea that would help companies and institutions store large chunks of data for a lifetime who develop data more than they can store. It is the fictional idea of DNA storage.
According to our biological concepts, DNA works as an information-storing molecule; involved greatly in transmitting genes from generation to generation which carry the blueprints for creating the human body. DNA stores information in four-letter DNA code whereas digital devices store them in two-letter code.
The digital information can be converted to DNA by translating the two codes. Once the transformation is made, strings of DNA can be made to carry the new code along with the information in that code. Once the digital code has been converted to DNA code, the scientists have to customize the DNA which would involve the creation of 10 million short strings of DNA.
A machine used by Twist Bioscience of San Francisco creates the strings letter by letter which can build up to 1.6 million strings at one go. Each string contains a fragment of information from a digital file with a chemical tag indicating the file from which the information came.
The major achievement from this technique would be durability. DNA sequences from fossils and older life forms can be used to recover primitive information which can exist for thousands of years. DNA information also takes up less space. This means that all publicly accessible data over the internet can be stored in a space resembling a shoebox.
DNA storage would avoid redundancy, thereby eliminating copies of stored information in new formats with rapidly changing reading modes.
