DNA computers

What is DNADNA means Deoxy-ribo-Nucleic Acid

It is the primary genetic material in a living body

Basic pairAdenine(A) pairs with Thymine(T)Guanine(G) pairs with Cytosine(C)

DNA Computer It is a computer made up using DNA

Introduction

DNA computers

Need for DNA Computer

Silicon processors has limited speed

Moore’s Law

Scientist found DNA has capability to be used to build a computer

Vast availability of Raw Material

DNA computers

In 1994, leonad Adleman, scientist at the university of California, introduced the idea of using DNA to solve complex mathematical problems.

He inspired by the book “Molecular Biology of the Gene”- written by James wastgon, who discovered the structure of DNA in 1953.

He used DNA to solve the complex Hemilton Path Problem.

Components of DNA Computer

Logic gate (“And Gate”) :

Developed at Uni. Rochester

Made up of DNA instead of Silicon

Biochip :

Logic gates can be combined with DNA micro chip to make Bio Chip.

DNA computers

First DNA Computer (Developed by Olympus Corp, Japan)

DNA computers

Olympus Optical co. ltd develop first DNA computer for Gene analysis in Japan,Conjunction with Akira Toyama, Assistant Professor of Tokyo university.

Aim to lead world to make a practical DNA Computer.

They made DNA Computer on February 15,2001 they established an R&D based joint DNA Computer.

DNA computers

Main Features of Dna Computer(made by Olympus corp.)

Parallel processing

Huge memory capacity

Variety of genes diagnostic and genes analysis

High precision

High speed

Low cost

Short time required

DNA computers

Construction of first DNA Computer

DNA computers

Construction (contd…)

Artificial DNA fragment , designed by using special software which has special property physicochemical that make up memory.

Allows scientist to observe chemical reaction.

Start gene analysis using the DNA computer on trial basis for a year.

DNA computers

Advantages

Many time faster

Capable of storing billions

of times more data than Silicon

Compact

Accurate

Efficient

DNA computers

Advantage of DNA over silicon

Cellular supply of DNA make it a cheap resource.

Made very cleanly.

Many time smaller than silicon.

One pound DNA capacity is to high.

Computing speed of One teradrop speed is most powerful.

(contd…)

DNA computers

10 trillion DNA molecules can fit into 1 cubic centimeter, able to hold 10 terabyte of data and perform 10 trillion calculation at a time.

Parallel processing.

DNA computers

Disadvantages

First developed DNA computer is so far from silicon-based computer in terms of speed.

It takes few days to narrow down possibilities.

It needs constant human assistance.

DNA computers

Applications of first generation DNA Computers

Gene analysis.

Useful to Government to break secret codes

To Airlines to map efficient routes

To understand about human Brain – the natural Super Computer

DNA computers

Future

Future is very bright to solving complex problem.

If research gets successful, it will eliminate the Silicon based Super Computers.

More powerful dna computers are likely to be introduced very soon.
