Buried deep inside nearly every cell of your body, tiny strands of DNA help determine who you are, how you look and explain in detail how to build and operate a human being. Over the last sixty years, scientists and researchers have learned how to decipher more of human genome. Moreover, diverse encoding models for reading and writing data onto DNA, codes for encrypting data which addresses issues of error generation, and approaches for developing codons and storage styles have been developed over the recent past. DNA has been identified as a potential medium for secret writing, which achieves the way towards DNA cryptography and stenography. DNA utilized as an organic memory device along with big data storage and analytics in DNA has paved the way towards DNA computing for solving computational problems. This article stresses the possibilities and scientific breakthroughs that genomic revolution brought to modern humans and armed them with technological tools and huge knowledge.
