Benefits of technology

[0007] With a careful coding scheme and arrangement, applicants have invented a process to encode data or information as an artificial DNA strand and store it in a living host safely and permanently. The instant invention can be used to identify origins and protect R&D investments (i.e., DNA watermarking) such as agricultural products and rare animals. For example, the present invention allows for storage of data that comprises specific information about the host organism. The agricultural industry can use this invention to “label” crops. By storing various data regarding the particular plant, including origin, type, generation, etc., the agricultural industry can then rely on this information at a later date (e.g., when produce hits the market). It can also be used in environmental research to track generations of organisms and observe the ecological impact of pollutants. Today, there are microorganisms that can survive heavy radiation exposure, high temperatures, and many other extreme conditions. These hardy microorganisms can serve as memory hosts and protect the stored data or information. There are living organisms such as weeds and cockroaches that have existed on earth for hundreds of millions of years. These organisms are excellent candidates as well for preserving critical information for a future civilization.

Problems solved by technology

A data preservation problem looms large behind today's information superhighway.
People or natural disasters can easily destroy all of them intentionally or accidentally.
However, a naked DNA molecule can easily be destroyed when exposed to unfavorable environmental conditions such as excessive temperature or dessication / rehydration.
Even nucleases in the environment may degrade the DNA molecules over time.

[0032] DNA Host Identification—Two well-understood bacteria, Escherichia coli (E. coli) and Deinococcus radiodurans (D. radiodurans), were utilized for our experiment. We selected E. coli and D. radiodurans because microorganisms, in general, grow very rapidly and the embedded information can be inherited rapidly and continuously. Deinococcus, survive extreme conditions such as ultraviolet, desiccation, partially vacuum environments, and ionizing radiation up to 1.6 million Rad (about 0.1% of the same radiation dose would be fatal to human beings). Some strains of Deinococcus can also tolerate high temperature. Although bacteria were chosen as preferred embodiments, it is understood that any living cell, whether single-celled or multicellular organism, can be used in the use of this invention.

[0033] Information Encoding—A (Adenine), C (Cytosine), G (Guanine), and T (Thymine) were used to assemble a DNA sequence information stream to represent data. Table 1 depicts the encoding key ...

Abstract

Current technologies allow the generation of artificial DNA molecules and / or the ability to alter the DNA sequences of existing DNA molecules. With a careful coding scheme and arrangement, it is possible to encode important information as an artificial DNA strand and store it in a living host safely and permanently. This inventive technology can be used to identify origins and protect R&D investments. It can also be used in environmental research to track generations of organisms and observe the ecological impact of pollutants. Today, there are microorganisms that can survive under extreme conditions. As well, it is advantageous to consider multicellular organisms as hosts for stored information. These living organisms can provide as memory housing and protection for stored data or information. The present invention provides well for data storage in a living organism wherein at least one DNA sequence is encoded to represent data and incorporated into a living organism.

Description

[0001] This invention was made with Government support under Contract DE-AC0676RL01830 awarded by the U.S. Department of Energy. The Government has certain rights in the invention.FIELD OF THE INVENTION [0002] The present invention relates generally to a method of storing data. In particular, but not exclusively, the present invention relates to storage of data as encoded DNA in living organisms. BACKGROUND OF THE INVENTION [0003] A data preservation problem looms large behind today's information superhighway. All current storage (e.g. paper, magnetic media, silicon chips) media require constant attention to maintain their information content. People or natural disasters can easily destroy all of them intentionally or accidentally. With the large amount of information generated by our society every day, it is time to think of a new generation of data memory. [0004] The use of deoxyribonucleic acid (DNA) as a component of memory storage has been proposed for a number of reasons. For ...
