Biocomputing or DNA (Deoxyribonucleic Acid) computing or biological computing, also known as molecular computing, is a new approach to massively parallelParallel computation. DNA computing was introduced as the means of solving a class of intractable computational problems in which the computing time can grow exponentially with problem size (the ‘NP-complete’ or non-deterministic polynomial time complete problems). A DNA computer is basically a collection of specially selected DNA strands whose combinations will result in the solution to some problems depending on the problem at hand.
