ABSTRACT
The biological research in the field of information technology paves the exploitation of storing capabilities, parallelism and also in conservative cryptography which enhances the security features for data transmission. DNA is the gene information which encodes information of all living beings. Though the DNA computing has its application in the field of huge information storage, massive parallel processing, low energy consumption which have been proposed and proved by the researchers and soon the molecular computer can replace the existing silicon computer and it exploits the world smallest computer. The combination of DNA molecules can be interpreted as a result to give a solution to a specific problem. The DNA strands can be replicated 500 times per second with greater accuracy. It can also be used in the field of cryptography based upon the vast parallelism which is used to break the existing cryptographic approach. This paper analysis an existing approach to the DNA computing method and DNA based cryptographic approach which provides the clear idea and limitations of existing research works.

1. INTRODUCTION
In the year 1994, Adleman[1] sets the step for the biocomputing research which introduced the idea of DNA to solve the complex mathematical problem and also he concluded that DNA has computational latent. He got this idea from the book “Molecular biology of the gene” which was written by James Watson who discovered the structure of DNA in 1953. His idea is to solve the unsolvable problems in the computer field using chemistry by conservative computers which requires a vast amount of computation. The idea of DNA computing involves the study of mathematics, biology, and chemistry and computer science. The biological researchers proved that DNA is similar to computer (i.e.) Logic gates are used in the silicon based computer which is used to transmit signals from the binary codes. He solved the directed HPP (Hamiltonian Path problem) with seven vertices in graph which the molecules are encoded in a sequence and the computation is performed by biochemical operations. Lipton [2] solved another NP-complete, the satisfaction problem which can also be called as searching algorithm .This study ascertained how problems analogous to

Boolean formulas are solved using extremely parallel [12] processing method. Such a method makes use the facility of DNA sequences that hybridize specifically to their complementary sequence. In 1953, Watson [3] discovered the structure of DNA is actually a double helix; The first DNA computer was developed with a concept of “DNA strands are useful to encode a information”. He solved the problem in the molecular biology laboratory, in which he did experiment using Hybridization, Gel separation and PCR (Polymerase Chain Reaction) sequencing by handling DNA sequences in a test tube. Clelland [4] (1999) have demonstrated an approach to steganography by hiding secret messages encoded as DNA strands among a multitude of random DNA. He used substitution cipher for encoding a plaintext where a unique based triplet is assigned to each alphabet, numeral and characters. The DNA offers efficient parallel [12] molecular computation and huge storage which has been proved by the researchers is used in the various applications by solving the issues such as expansive and time consuming problems. The amplification technology of DNA is PCR (Polymerase Chain Reaction). It is tremendously difficult to amplify the message encoded sequence without...
