Development in steganography cares about increasing the amount of secret data embedded with a carrier. DNA file as a cover media is the best choice for that manner to increase the data embededd. This paper presents steganography with DNA files and proposes a new method to embed secret data in DNA files using genetic algorithm to enhance the performance and care with the steganography performance measures. The proposed method solves the problems of substitution method, using genetic algorithm to choose the best positions in the DNA file, to embed secret data, make the modification rate equal 0 in most cases and the lowest in other cases, and reduce the list generated. The cracking probability of the algorithm is very low. For more security, the secret data are encrypted with RSA algorithm before embedding. Final experiment results show an improvement in modification rate of the carrier.
