DNA- DIGITAL DATA STORAGE 

    - By S Sneha




As we all know , DNA is the one of the smallest molecules capable of storing all the genetic information about a person. The DNA has a very  highly coiled structure . The most astonishing fact is the capacity of DNA to  store up to 215 petabytes of information in a single gram of its unit. A team of interdisciplinary researchers have come up with innovative techniques to use the DNA for storing digital information. Information is being produced at exponentially high rates and there is an essential need to store this information very efficiently and for a longer period of time. This process involves encoding and decoding binary data to and from synthesized strands of DNA . DNA based data storage  is both durable and compact.  DNA—which consists of long chains of the nucleotides A, T, C and G—is life’s information-storage material. Data can be stored in the sequence of these letters, turning DNA into a new form of information technology. The key breakthrough is an encoding algorithm that allows accurate retrieval of the information even when the DNA strands are partially damaged during storage. To demonstrate information retrieval from degraded DNA, the team subjected the DNA to high temperatures and extreme humidity. Even though the DNA strands were damaged by these harsh conditions, all the information was still decoded successfully. This method is 5 million times better than the current data storage method since DNA has a very high data storing capacity, can be stored easily at room temperature for thousands of years. But this technique also has its own limitations. It is very expensive and has a slow read and write time and is also prone to errors. The proposed technique has been very  remarkable and has a promising potential in the future.
