- 1. DNA Computer β’ Presented by:- Shahenaz Aghariya Roll no :- 02 (6th IT)
- 2. Introduction To DNA Computer β’ Store Billions of time more information. β’ High computing speed. β’ Information is encoded within βDeoxiribo Nucleic Acidβ. β’ First Demonstrated By Ad leman in 1994.
- 3. Some information about DNA β’ Definition of DNA β’ About nucleic acid β’ Genes and chromosomes
- 4. Structure of DNA β’ Strands of DNA are long polymers of millions of linked nucliotides. β’ Nitrogen bases . β’ 5β to 3β direction. β’ Double Helix form. β’ Purin and pirimidin bases.
- 5. Operations on DNA β’ Merge β’ Annealing β’ Melt β’ Separation by length - Electophoresis. β’ Separation by sequences β’ Copying / Amplification β’ Append β’ Detect
- 6. Adlemanβs Hamilton Path Problem β’ Why his work is exceptional?
- 7. Adlemanβs Expriment Following are the steps used by Adleman. 1.Generate all possible routes 2.Select journey that start with proper city and end with final city. 3.Select journey with the correct number of cities. 4.Select journey that contain each city only once.
- 8. How DNA Computer will work? β’ Development of logic gates made of DNA.
- 9. Comparison between DNA and conventional electronic computer β’ Similarities:- 1. Transformation of data 2. Manipulation of data 3. Computation ability β’ Differences:- 1. Size 2. Representation of data 3. Material 4. Methods of calculation
- 10. Advantages β’ Parallelism β’ Memory capacity β’ Low power dissipation β’ Clean,cheap and available
- 11. Key benefits β’ Predictability β’ Incredibly cheap β’ Small size
- 12. Drawbacks β’ Occasionally slow β’ Hydrolysis β’ Information on transmitable β’ Reliability problems
- 13. Conclusion β’ I would like to conclude by sharing a future vision in which a single drop of water holds a veritable army of live robots for protection against various diseases may be even cancer. β’ It is still science fiction but implanting computer programs in to living creatures may not be far away.
