Abstract:
Various attributes of DNA that can facilitate computing in solving complex problems by using the concepts of computing and biology are presented here. The silicon based computers do only what is told (and how), are becoming very small with increasing speed but how long this mechanism of decreasing chip size and increasing the speed of current computation will continue. Todayâ€™s personal computerâ€™s silicon chip consists of 50 to 60 million transistors on a small sized IC. According to quantum physics, if the silicon chip continues to decrease, it will reduce the effective transmission of signals. Computer chips are made of toxic substances such as arsenic which can cause damage to nerve cells and immune system especially in children. Silicon based chips consume lot of energy and dissipate heat. DNA computing on the other hand has the potential such as parallel & distributed processing, massive storage of data, scalable, adaptive (through learning or evolution) and flexible to minimize costs, to solve the complex NP problems that are difficult to solve by the current computation. The ultimate goal of this paper is to explore technical dimensions of DNA computing by identifying the new uses of nucleic acids, problems, right questions, DNA molecules potentials.
