- 8. Bio Chemical Computers BioChemical Computers use the immense variety of feedback loops that are characteristics of biological chemical reactions in order to achieve computational functionality . Feedback loops in biological systems take many forms and many different factors can provide both positive and negative feedback to a particular biochemical process ,causing either an increase in chemical output or a decrease in chemical output respectively.

This Photo byUnknown Author is licensed under CC BY-NC Such factor may include the quantity of catalytic enzymes present ,the amount of reactants present , the amount of products present , and the presence of molecules that bind to and thus alter the chemical reactivity of any of the aforementioned factors . Given the nature of these biochemical systems to be regulated through many different mechanisms , one can engineer a chemical pathway comprising a set of molecular components that reacts to produce one particular product under one set of specific chemical conditions and another particular product under another set of conditions
- 10. The presence ofthe particular product that results from the pathway can serve as a signal ,which can be interpreted along with other chemical signals as a computational output based upon the starting chemical conditions of the system the (input).
- 11. Bio Mechanical Computers BiochemicalComputers are similar to biochemical computers in that they both performs a specific operation that can be interpreted as a functional computation based upon specific initial conditions which serve as input . They differ , however in what exactly serves as the output signal .In biochemical computers ,the presence or concentration of certain chemicals serves as the output signal . In biochemical computers , however the mechanical shape of a specific molecule or set of molecules under a set of initial conditions serves as the output .
- 12. Bio Mechanical Computersrely on the nature of specific molecules to adopt certain physical configurations under certain chemical conditions. The mechanical , three - dimensional structure of the product of the biomechanical computer is detected and interpreted appropriately as a calculated output

- 15. Bio-Electronics Computers Again likeboth biomechanical and biochemical computers , computations are performed by interpreting a specific output that is based upon an initial set of conditions that serve as input . In bioelectronics computers , the measured output is the nature of the electrical conductivity that is observed in the bioelectronics computer. This output comprises specifically designed biomolecules that conducts electricity in highly specific manner based upon the initial conditions that serve as the input of the bioelectronics system.

- 17. Bio Computers asSuccessor to Silicon Computers store data in strings made up of 0 & 1 . Living things store information with molecules representing the letters A,T,C & G. A single gram of DNA can hold a much information as a trillion compact disc
- 19. Advantages Ample supplyof raw materials It can be made many times smaller than today’s computer No toxic by products
- 20. Disadvantages Time consuming Occasionally slower Human Assistance
- 21. Comparison… DNA COMPUTERS Slowat single operation Able to simultaneously perform millions of operation Huge storage capacity Require considerable preparation before CLASSICAL COMPUTERS Fast at single operation Can do fewer operation simultaneously Smaller capacity Immediate setup
- 22. Conclusion… It isn’t tohard to imagine that one day we might have all the tools and talent to produce small integrated desktop machine that uses DNA or a DNA like biopolymer as a computing substrate along with the set of designer enzymes.
