Definition of DNA computing in security?

Answer 1

DNA computing, also known as molecular computing, is a new approach to massively parallel computation based on groundbreaking work by Adleman . In November of 1994, Dr. Leonard Adleman wrote the first paper on DNA computing. In this paper, he found a way to solve the "Hamiltonian path problem," which involves finding all the possible paths between a certain number of vertices. It is also known as the "traveling salesman problem." This name comes from viewing each vertex as a city, with the problem to find all possible routes for a salesman passing through each of these cities . Computers today all use binary codes - 1's and 0's or on's and off's. These codes are the basis for all possible calculations a computer is able to perform. Because the DNA molecule is also a code, Adleman saw the possibility of employing DNA as a molecular computer. However, rather than relying in the position of electronic switches in a microchip, Adleman relied on the much faster reactions of DNA nucleotides binding with their complements, a brute force method that would indeed work A DNA computer is a collection of DNA strands that have been specially selected to aid in the search of solutions for some problems. DNA computing results in parallelism, which means that when enough DNA information is given, huge problems can be solved by invoking a parallel search
