Dna Technology to Store Digital Data
Chapter-1
Introduction
1.1 Motivation:
Since time immemorial, mankind has wanted to share and use information for later use. First, it was through the caveman paintings and symbols. Then we invented the alphabets, ideograms, numbers and other symbols. Using these, books were written and stored for future generations, in palm leaves, papyrus sheets or paper. The invention of printing brought the Gutenberg revolution, making multiple copies easily and spreading education to millions of people. Printed books occupy space. Libraries and archives are bursting at the seams. Enter the computer age and digitization using the binary code of combining zeros and ones (0,1) for alphabets and other such symbols, and reading them using the on-off electrical signals, which has made electronic storage possible, cutting down the size and space for ‘hard copies’. Integrated circuits, processors and related electronic wizardry have shrunk the size of computers and storage devices from room-size to finger nail size. Digital information is accumulating at an astounding rate, straining our ability to store and archive it. Hard drive storage has been made cheaper, faster and larger. Disk storage technology in general has seen incredible advances including reduction in size, an increase in real density, and an increase in internal data rates, but the future of hard disk technology is uncertain. Digital production, transmission and storage have revolutionized how we access and use information but have also made archiving an increasingly complex task that requires active, continuing maintenance of digital media. This challenge has focused some interest on DNA as an attractive target for information storage because of its capacity for high-density information encoding, longevity under easily achieved conditions and proven track record as an information bearer.
1.2 Problem Statement:
Previous DNA-based information storage approaches have encoded only trivial amounts of
