Computer applications have become an essential part of our daily lives, and their use is flourishing day by day. In Conventional Computer, there are lots of limitations like: Operational Speed, Power Consumption, Parallel Processing, Hardware Size, Data Storage Limitation, etc. To emphasize the problem, the paper provides A Proper Approach on DNA Based Computer. DNA Based Computer is a nano-computer that uses DNA (DeoxyriboNucleic Acids) to store information and perform complex calculations with low power consumption in a matter of seconds. The paper proposed Design Methodology of DNA Computer. Also various features of DNA Computer and operation of its processing units are reviewed. An overview on Adleman Experiment is also included in the paper.
