BIOLOGICAL COMPUTERS
BIOLOGICAL COMPUTERS.ppt (Size: 519.75 KB / Downloads: 63) INTRODUCTION Growing needs of mankind-Rapid Development. Rapid advancement in computer technology will lose its momentum when silicon chip reaches its full capacity & miniaturization Solving complex problems which today's supercomputers are unable to perform in stipulated period of time. WHAT COULD BE A REMEDY TO THIS CONCERN? Biological computers Biological computers are special types of microcomputers that are specifically designed to be used for medical applications. The biological computer is an implantable device that is mainly used for tasks like monitoring the body's activities or inducing therapeutic effects, all at the molecular or cellular level. The biological computer is made up of RNA (Ribonucleic Acid – an important part in the synthesis of protein from amino acids), DNA (Deoxyribonucleic Acid - nucleic acid molecule that contains the important genetic information that is used by the body for the construction of cells; it's the blue print for all living organisms),and proteins. Biocomputers constructed entirely of DNA, RNA and proteins can function inside the body as "molecular doctors”. How It Works Biological computers are made inside a patient's body. Each human cell already has all of the tools required to build these biocomputers on its own. The researchers or doctors merely provide the patient's body with all of the necessary information or a "blueprint" along which lines the biological computer would be "manufactured." Once the "computer's" genetic blueprint has been provided, the human body will start to build it on its own using the body's natural biological processes and the cells found in the body. All that must be provided is a genetic blueprint of the machine and our own biology will do the rest. Our cells will literally build these biocomputers for us. As of today, reading signals produced by cell activity is not yet possible due to technological limitations. However, through the use of a tiny implantable biological computer, these cellular signals could easily be detected, translated and understood using existing medical and laboratory equipment . Through boolean logic equations , Doctor or researchers can use the biological computer to identify all types of cellular activity and determine whether a particular activity is harmful or not. The cellular activities that the biological computer could detect can even include those of mutated genes and all other activities of the genes found in cells. As with conventional computers, the biological computer also works with an output and an input signal. The main inputs of the biological computer are the body's proteins, RNA, and other specific chemicals found in the human cytoplasm. The output on the other hand could be detected using laboratory equipment. Adleman-Inventor of Biological Computers Leonard Adleman of the University of Southern California in the US used different strands of DNA to represent the 20 variables in their problem, which could be the most complex task ever solved without a conventional computer. The complexity of the structure of biological molecules could allow DNA computers to outperform their electronic counterparts in future. His article released in 1994,described how to use DNA to solve a well-known mathematical problem, called the directed Hamilton Path problem. Goal of the problem is to find the shortest route between a number of cities, going through each city only once. |
