1. DATA STORAGE IN DNA

2. CONTENTS: Introduction What is DNA? Why we are preferring DNA as an information storing device? How information is stored in DNA? Advantages Disadvantages Future scope Conclusion

3. INTRODUCTION Since time immemorial mankind wanted to share information for later use. Starting from the caveman paintings and symbols,we have entered into the computer age and digitalization. At present we have so many storage devices like hard discs,magnetic tapes and pendrives etc. But even so,the amount of information to be stored is growing exponentially.

4. “That means cost is increasing but our budgets are not” So it’s the time to use innovative substitute i .e ., long lived , stable and easily synthesized. That is nothing but DNA

5. WHAT IS DNA? Deoxyribo nucleic acid. It is a molecule that encodes the genetic instructions. Most DNA molecules are double stranded helices. Each molecule consists of two long biopolymers made of simpler units called nucleotides-each nucleotide is composed of a nucleobase recorded using the letters G,A,T and C. DNA is well suited for biological information storage.

6. Structure of DNA

7. Why we are preferring DNA as an information storage device? Companies,governments and universities face an enormous challenge storing the ever-growing flood of digitized information. Some experts have looked for answers in biology.In recent years,they have found ways to encode trademarks in cells and poetry in bacteria. But these biological things eventually die.By contrast,DNA is stable,durable and dense. DNA could hold vastly more information than the same surface volume of a disk drive.

8. How information is stored in DNA?

9. Example of existing technology : DNA chip

10. How much information can be stored in DNA? Goldman and co have been able to store 2.2 petabytes in one gram of DNA.DNA would allow at least 100 million hours of high-definition video to be stored in a teacup.

11. What did goldman and group store in Dna ? 1.They stored all 154 sonnets of shakespeare (in ASCII text). 2.The 1953 watson -crick paper on the DNA double helix(in pdf format). 3.A colour photograph of Hinxton (in JPEG) and 4.A clip from the “I have a dream” speech of Martin luther king (in Mp3 format).

12. Features of DNA for using it as an information storage device: Long lived,stable and easily synthesized. Needs no active maintenance. Stores digital files without electricity for thousand of years. Last for tens of thousands of years. We can store a 2.2 petabytes in one gram of DNA. Highly reliable.

13. Disadvantages: Today the speed is low. Cost is high.

14. Future Enhancement: Goodbye silicon , Hello DNA. The future of data storage device. DNA can be used in: 1.DNA Computing. 2.DNA Nanotechnology.

15. Conclusion: The longer you want to store information then , the more attractive DNA becomes . And the cost of sequencing and synthesising DNA is falling fast. “There is no problem with holding a lot of information in DNA”. “The problem is paying for doing that”.
