The present study delineates Deoxyribonucleic Acid (DNA) based computing and storage devices which have good future in the vast era of information technology. The traditional devices mostly used are made up of silicon. The devices are costly and have physical limitations to cause leakage of electrons and circuit to shorten. So, there is a need of materials which are capable of doing fast processing and have vast memory storage. DNA which is a bio-molecule has all these characteristics capable of providing ample storage. In classical computing devices, electronic logic gates are elements which allow storing and transforming of information. Designing of an appropriate sequence or a net of “store” and “transform” operations (in a sense of building a device or writing a program) is equivalent to preparing some computations. In DNA based computation, the situation is analogous. The main difference is the type of computing devices since in this new method of computing instead of electronic gates, DNA molecules have been deployed for the processing of dossier. Moreover, the inherent massive parallelism of DNA computing may lead to methods solving some intractable computational problems. The aim of this research study is to analyze the logical features and memory formation using DNA bio molecules in order to achieve proliferated speed, accuracy and vast storage.
