In biological language DNA means Deoxyribonucleic acid. It accommodates all most all the information about a particular body that how the body looks, what he eats, what were his body posture and many more things. Data storage in DNA is now really possible. An outstanding technology has been evolved by which we can store a very large aggregate of data in DNA and can also recover it.
Any data stored can be recovered even after thousands of years. That means DNA has a capability to store data for a long duration of time.
Any digital data that we store are stored in the form of binary codes of 010101. But a data that are stored in DNA are in the form of genetic codes of APCG. That means if we need to store a digital data in DNA then we need to convert it into genetic codes. It is said as Digital Data Storage.
On 16 August 2012 an experiment was held at Harvard University where data storage technology in DNA was evolved. A data was stored in DNA and was successfully recovered. The stored data was 3 jpg images.
According to the experiment, in 1 millimetre of cube of DNA can reserve at least 1 Exabyte of information that is 1000000000 GB. All the data that is stored on the internet is approximately of 15 Zettabyte that is 15,000,000,000,000 GB.
According to the technique of data storage in 1 cm cube of DNA we can store 1 Zettabyte of information. In other words it can be said that all the data present on the internet can be stored in a cup of tea like DNA structure.
World biggest company of Bill Gates Microsoft Research computer architects say they want to start storing their data on strands of DNA within the next few years, and expect to have an operational storage system using DNA within a data centre by the end of the decade.
Data storage in DNA has two negative points :-
>The data recovery time is slow.
>This technology is quite expensive.
At last but not the least this technology of data storage is really very effective; scientists are working on it to make it more reliable and advantageous. If everything goes right then till 2025 this technology will may be widely used to accumulate large quantities of data.
