Digital Storage Breaking New DNA into Stored Data "New Weapons" [Full Text]

Posted on

Scientific and technological developments in recent years, a number of storage technology experts set their sights on bionics. They argued that life is so delicate and complex that in order to be able to reproduce hereditary mistakes, even if it is a jealousy, it carries enough information to fill a room full of hard drives. How do you store this data with your little body? The answer is DNA (deoxyribonucleic acid). DNA is the basic structure of genetic and genetic coding, and its function is mainly semi-reserved replication (lasting life) and transcription of ribonucleic acids to synthesize proteins (to achieve life function).

According to foreign media reports, scientists have made breakthroughs in digital storage, allowing information to be stored in a single DNA molecule for millions of years. This breakthrough allows us to build digital archives and store all the information in the form of DNA. This method can theoretically save information for hundreds of thousands of years without any data loss.

DNA has 4 bases, and there are many more possibilities in coding, and many advantages will emerge from it. The most obvious advantage is capacity. DNA itself is a "database" that carries massive amounts of genetic information. In human genetic sequences, 1 gram of DNA contains billions of gigabytes of genetic data, and according to American scientist George Church in 1 Shaq (billion). One-tenth of a gram) The amount of data stored in DNA translates to as much as 700TB of data that can be stored in one gram of DNA, equivalent to 14,000 Blu-ray Discs, or 233 3TB hard disks.

Robert Grass and colleagues at the Swiss Federal Institute of Technology stated that they have found a way to encapsulate DNA in new glasses. This is equivalent to creating a fossil record of data. They also created a mathematical algorithm commonly used for long-distance wireless transmissions to eliminate data errors when writing DNA. The researchers said they showed how to use modern chemistry and information engineering tools to protect data stored in the form of DNA.

Dr. Grass said: "After discovering the double helix structure of DNA, people discovered that the coding language of nature is very similar to the binary language we use in the computer field. On hard disks we use 0 and 1 to represent data, and in DNA We have 4 forms of nucleotides, A, C, T and G."

Synthetic DNA molecules can be stored at 71 degrees Celsius for a week, which is equivalent to being able to store at 50 degrees Celsius for 2,000 years. And when the information was recompiled into the original information, no errors occurred.

The problem faced by this technology is not the current high cost of using DAN to store information, but rather the inability to quickly and easily retrieve information. Dr. Grass said: "At this stage we can only read all the information stored in it, but can not point to a specific location to read only one file."
