Storing Digital Data in Nucleic Acid Memory with Extended Genetic Alphabet

The rapid improvement of semiconductor technologies have led to a digital revolution globally which accelerated the rate of generation of data exponentially. When researchers are working hard to develop better compression algorithms, they came up with the idea of Nucleic Acid Memory (NAM). Various papers have been studied with their respective merits and demerits. This paper proposes a new scheme of encoding digital data into genetic nucleotide sequence which demonstrates the use of non-standard nucleotides and unnatural base pairs along with standard nucleotide bases. This combination aims in enhancing the efficiency of the encoding scheme much better than the predefined encoding model where the proposed scheme is compared with the existing encoding models.
