DNA as a carrier of information
The topic of information storage is highly relevant. That's why companies, like Microsoft, invest in research, where geneticists try to use DNA to store data.
The DNA itself contains information about the body. It encodes everything: looks, physical abilities, inclinations for one or another disease. This makes deoxyribonucleic acid an ideal material for storing information in the future.
DNA is better than most existing storage facilities.
It does not decrease over time. Just imagine: 4 grams of DNA can contain information produced by all humans in a year!
The propensity of growing media capacity has been the norm for the last few years, and the need for more memory has not disappeared. We need something more reliable and broader than before. The answer is DNA. The study, published by Yaniv Ehrlich and Dina Zelinski in the Journal of Science, shows this.
Two researchers used 72,000 DNA strands (each 200 long bases) and stored six files:
French film of 1895
Amazon gift cards
Complete computer OS
computer virus
The study of an expert in information technology, Claude Shannon
Pioneer signboard
"We compared nucleotides in nucleotides." Then we synthesize these nucleotides and store them in a test tube, "Erlich told ResearchGate." To package the information, we developed a strategy - what is called DNA fountain - which uses the mathematical concepts of coding theory. "That is a strategy that allows us to reach packaging optimal, which is the most difficult aspect of research. "
After that, they extract the data using DNA sequencing technology, and then transfer the data into binary form using the software. "To get information, we regulate molecules.This is a fundamental process," Erlich said.
Great capacity and endurance
Ehrlich is why DNA is better than the method of storing information that exists. He says that DNA has several major advantages, which are primarily ultra-small. The volume of information storage is impressive - it can reach 215 petabytes per gram of DNA, and can be stored for a very long time. Duration may exceed 100 years, which is an order of magnitude larger than the lifetime of traditional operators.
This study proves: for future DNA data storage.
Ehrlich expressed his conviction that it was time to move on to better technology. "The information carriers will quickly become obsolete, my parents are using a 8 millimeter tape, which is currently useless," he added. "DNA is about 3 billion years old, and humans are unlikely to lose the ability to read these molecules." If this happens, we will have a different scale. "
When asked how long this technology would take for everyone, Erlich responded optimistically. "I think it will take more than 10 years," he said. "We are still at the beginning of the journey, but even in the field of magnetic media development that it took years before they became public."
