Scientists working toward storing digital information in DNA

Scientists are working towards storing digital data in the base sequence of DNA (Deoxyribonucleic acid). 

•    Thus they are seeking to make the genetic material capable to store data for long time in durable format as an archive data for the future. 
•    The information in the DNA is stored in strings i.e. in the form four-letter DNA code. It is basically sequences of four building blocks (nuclear strands) abbreviated as A (Adenine), C (Cytosine), T (Thymine) and G (Guanine) found in DNA molecule. 
•    Basically digital devices store information in binary format (1s and 0s) i.e. in a two-letter code that produces strings of 1s and 0s. 
•    The DNA digital data storage technology uses artificial DNA made using oligonucleotide synthesis machines for storage and DNA sequencing machines for retrieval of stored data. 
•    Using this technology strings of DNA can be custom-made that can carry the new code, and store information that code contains
