Dna Computing: A Review

Abstract--All computers in existence today make use of binary code – 1’s and 0’s, or on’s and off’s on the circuits of computer chip, forming the basis for every calculation a computer performs, from simple addition to the solution of most complex differential equations. Since the DNA molecule is also code, but instead made up of a sequence of four bases which pair up in a predictable manner, it has the possibility for being used as a molecular computer. DNA computing holds out the promise of important and significant connections between computers and living systems, as well as promising massively parallel computations. DNA computing devices could revolutionize the pharmaceutical and biomedical fields. But before these promises are fulfilled important challenges related to errors and practicalities have to be addressed. Nevertheless, DNA computers seem to be the future
