The present study included an application of new method of steganography using DNA sequence as a medium for hiding. This method is considered as a secret cover for the secret message (text, image), avoid attention of unauthorized person in addition to be inextricable since it needs high effort, long time and well background in biology. A Sequence of DNA has been synthesized chemically depending on the text secret message via using tables of symbols formed from English letter, numbers and special characters. Each symbol has been represented on codon and the symbols were arranged in the table in descending order depending on English letter frequency and codon frequency (Genes). The DNA sequence has been synthesized by Korean Bioneer Company (sender), then the sequence has been read in university of fatih (the receiver) by DNA Sequence 3310, the results revealed high similarity between sequence of the sender and receiver. And proved that the method is protected very well against analysis and stegoanalysis.
