What is DNA Digital Data Storage.
                     WHAT IS DNA 
DIGITAL DATA 
STORAGE?
INTRODUCTION
• DNA digital data storage is the process of encoding 
and decoding binary data to and from synthesized 
strands of DNA. 
• While DNA as a storage medium has enormous 
potential because of its high storage density, its 
practical use is currently severely limited because 
of its high cost and very slow read and write times.

ALTERNATIVE TO HARD DRIVES
• An alternative to hard drives is progressing DNA-
based data storage. DNA—which consists of long 
chains of the nucleotides A, T, C and G—is life’s 
information-storage material.

INFORMATION TECHNOLOGY
• Data can be stored in the sequence of these 
letters, turning DNA into a new form of 
information technology. 
• It is already routinely sequenced (read), 
synthesized (written to) and accurately copied with 
ease.

STORAGE CAPACITY
• But it is the storage capacity that shines. DNA can 
accurately stow massive amounts of data at a 
density far exceeding that of electronic devices.

PROSPECT OF DNA DATA STORAGE
• The prospect of DNA data storage is not merely 
theoretical. In 2017, for instance, Church’s group at 
Harvard adopted CRISPR DNA-editing technology 
to record images of a human hand into the 
genome of E. coli, which were read out with higher 
than 90 percent accuracy.

RECENT ADVANCEMENTS
• Recent advancements in next-generation 
sequencing techniques allow for billions of DNA 
sequences to be read easily and simultaneously. 
With this ability, investigators can employ bar 
coding use of DNA sequences as molecular 
identification “tags” to keep track of experimental 
results.

DNA BAR CODING
• DNA bar coding is now being used to dramatically 
accelerate the pace of research in fields such as 
chemical engineering, materials science and 
nanotechnology

ELECTRONIC STORAGE
• Among the challenges to making DNA data storage 
commonplace are the costs and speed of reading 
and writing DNA, which need to drop even further 
if the approach is to compete with electronic 
storage.

DNA SECRET WRITING
• Secret writing is used to prevent illegal access of 
information by unauthorized parties. Cryptography 
and steganography are two methods used for 
secret writing. 
• Cryptography manipulates information for 
misunderstanding while steganography hides the 
existence of information

THE FUTURE
•  Even if DNA does not become a ubiquitous 
storage material, it will almost certainly be used 
for generating information at entirely new scales 
and preserving certain types of data over the long 
term.
