Introduction What is DNA DNA means Deoxy-ribo-Nucleic Acid It is the primary genetic material in a living body Basic pair Adenine(A) pairs with Thymine(T) Guanine(G) pairs with Cytosine(C) DNA Computer It is a computer made up using DNA

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

Research • 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.

DNA computers

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.

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.

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.
