In this paper, we present a DNA number system to represent numbers in terms of DNA strands instead of numerical digits. Triplets of nucleotides, called codons, serve as digits in our DNA number system. In this number system, we distinguish integers from real numbers based on the length of the corresponding DNA sequence representation. Further in this paper, we describe a search method that performs the task in a unit time, irrespective of the input size. This method uses the novel idea of the DNA annealing property. We also propose a classical cryptosystem in terms of a DNA algorithm.
