Future aspects and Conclusion

It is clear that the DNA computers or molecular computers have many attractive properties. Some of their properties like extremely dense storage, enormous parallelism, their energy efficiency makes them ideal computer systems, it’s not a here-&-now practical technology20, it’s a pie-in-the-sky research project that needs lot of good ideas, hard work & luck to realize its potential12. As admitted by Prof. Ehud Shapiro, Weizmann institute of science, Israel, to BBC news that it seems to be really difficult to beat electronic computer by DNA computing method in foreseeable future. so a new goal in this field is to try to use DNA computing to do things that traditional computers cannot do.
From the above discussion it can be concluded that presently, DNA computer lies only in the theory, although, in some research institutes21 and universities such as university of southern California with Dr. Adleman, Princeton, Dr. Richard Lipton and his graduate students and other elsewhere are developing new branches in the young field. Advancement are being made in cryptography and Researchers are working on decreasing error in & damage to DNA during computation. But, a functional ‘DNA computer’ of the type that most people are familiar, lies many years in future.
