Store books right in DNA

US scientists have made a big breakthrough when successfully storing a book in DNA sequences, opening up the prospect of new-style information storage methods with much cheaper prices than using Current popular digital technology devices.

Deoxyribonucleotide or DNA is known as a chemical that contains genetic information in most living organisms. In terms of structure, any DNA sequence contains 4 types of nucleotides, A, T, G and C (some documents are called X or U).

In theory, each nucleotide can be used to encode a bit of data. However, in fact, the DNA molecule is a double helix made up of two single nucleotide strips and the nucleotides in each single string will combine together in accordance with AT and GC rules (X / U), so one The position on the DNA will correspond to 2 bits.

DNA has an impressive ability to store information.

Therefore, DNA has an impressive ability to store information. It is estimated that one millimeter of DNA block can store 1 million gigabytes (GB) and one gram of this molecule can store up to 455 billion GB of information, equivalent to the capacity of 100 billion DVDs.

With such a great ability, just 4 grams of DNA is enough to contain the entire amount of annual data that people create. Prior to the predictions of experts, the amount of data that people use will increase 2 times after 2 years and by 2020 data worldwide will be 50 times larger than today, if continue to use Current popular storage products will be extremely expensive, supply shortages and create huge amounts of waste products. So turning the idea of ​​storing DNA into reality will help people quickly solve these problems.

The Guardian newspaper reported that the research group led by Professor George Church from Harvard Medical School (USA) has recently released the technology to store information on DNA very practically even though the speed is still slow. The report, published in Science, said researchers used DNA to successfully encode an entire English book of 53,426 words, along with 11 JPG images and JavaScript code. It is known that the document capacity is equivalent to a 5.27 megabit binary range, 600 times larger than the recent achievement.

The achievements of American scientists have been hailed as a historic breakthrough, as well as opening up the prospect of producing biomarkers within five or 10 years.
