The document discusses DNA computing and its advantages over traditional computers. It begins with an introduction by Debadarshi Mishra on the topic. DNA computers use enzymes that react with DNA strands in a chain reaction to perform computations in parallel, unlike traditional computers that use binary. DNA computers are smaller, faster, and can solve problems with many possible solutions simultaneously. Their potential applications include monitoring health and generating customized drugs. While still in development, DNA computing represents a new approach to computation at the molecular level.

- 3. INTRODUCTION DNA computer is a molecular computer that works biochemically. It computes using enzymes that react with DNA strands causing chain reaction. The chain reaction act as a kind of stimulus computing or parallel processing
- 4. The field was initially developed by Leanard Aldman who 1994 demonstrated a proof of concept use of DNA as form of computation which was used to solve the seven point hemilton path problem. On april 28 2004 Ehud Sharpiro and researchers at Weizmann institute announced in the journal Nature that they constructed aDNA computer
- 5. How DNA works as a computer Electronic computers store data in binary form then resemble and interpret the information in meaningful way. A DNA computer has the same basic abilities to store information and compute solutions .But its working method is different. It works off molecular automations and preset reactions.
- 6. DNA computer as a part of nanoscience A DNA can monitor blood in vitro. IF a chemical imbalance is detected, the DNA computer can synthesize the needed replacement and release it into the blood to restore equilibrium. It can also eliminate the unwanted chemicals by disabling them at molecular level
- 7. Micro biotech DNA double helix
- 10. DNA computing In terms of speed and size however DNA computers surpass conventional computer. While scientist say silicon chips cannot further scaled down much further, the DNA molecule found in the nucleus of all cells can hold more information in a cubic centimeter than a trillion music cds. A spoonful of DNA contain 15000 trillion computers and energy sufficiency is more than a million times that of a pc.
- 11. Israeli scientists have devised a computer composed of DNA and enzymes. The enzyme breaks bonds in the DNA double helix, causing the release of enough energy for the system to be self-
- 12. It is smaller and faster than all modern day pcs. Pc is designed to perform one operation very fast .DNA computer can produce billions of potential answer simultaneously, which is suitable for solving ”fuzzy logic” problems that have many possible solution rather than either/or logic of binary computers. Benefits of DNA computing
- 13. It is a revolution in the field of pharmaceutical and biomedical fields.it can recognize cancerous cells when injected into body and generate drugs for it .Not only for cancer it can work for different diseases and will give quick remedy. cont’s….
- 14. DNA chip
- 15. conclusion Think of DNA as software and enzyme as hardware when put into a beaker the molecules undergo chemical reactions with each other allows simple operations to be performed as a byproduct of the reaction. it is completely different approach to passing electrons around a dry circuit in a conventional computer. So scientists are trying to make a hybrid computer which use traditional silicon chips for normal processing tasks but have DNA co- processors that can take over specific tasks.
