Method for storing information in DNA
First Claim
1. A method for storing information in DNA using a unique sequence of 4-DNA bases for representing each character of extended ASCII character set comprising:
- (a) producing a synthetic DNA molecule comprising encrypted digital information that can be decoded with the use of an encryption key, flanked on each side by a primer sequence; and
(b) storing the DNA molecule in a storage DNA, which consists of a mixture of homogenous/heterogeneous DNA

Abstract
DNA is a natural molecular level storage device. Molecular storage devices use each molecule or part of it for storing a character. Thus it is possible to store information million of times than presently used storage devices. For example a JPEG image (i.e. flag of India) having file size of 1981 Bytes can be encrypted using 7924 DNA bases which occupies about 2694.16 nanometers In other words flag of India can be encrypted 8.07×105 times in human genome which comprises 6.4×109 DNA bases and occupy a tiny volume of about 0.02 μm3. A method for storing information in DNA has been developed which includes software and a set of schemes to encrypt, store and decrypt information in terms of DNA bases. The main advantages of the present method over exiting art is that it addresses complete set of extended ASCII characters set and thereby, encryption of all kind of digital information (text, image, audio etc.). First of all, information is, encrypted along with carefully designed sequences known as header and tail primers at both the ends of actual encrypted information. This encrypted sequence is then synthesized and mixed up with the enormous complex denatured DNA strands of genomic DNA of human or other organism.

19. A DNA molecule comprising an encrypted DNA sequence that can be decoded with the use of an encryption key, flanked on each side by polymerase chain reaction primer sequences wherein amplification of the DNA molecule and determination of the secret message DNA sequence and use of an encryption key, results in a decryption of the message.
