DNA Computing of Transfer Closure Problems

The DNA calculation is a new computing mode,which combine and infiltrate computer science with molecular biol ogy.It has certain advantages in solving complex issues,particularly NP complete problems,which can provide a new solution.In the first place,the paper presents the basic principle of DNA computing.In the second place,the paper introduces the transfer clo sure DNA algorithm in detail.The graph vertices were encoded by DNA fragments.Then,these DNA fragments were put into the solution which can conduct biochemical reaction.The solutions are generated through the basic biological operation and bio logical enzyme.And finally,all transfer closure solutions were selected.Eventually,the paper gives an introduction about the DNA computing research and some problems to be solved in its.
