Since the beginning of human history, people have used it for the purpose of preserving data, different methods, new ways have been created. And in this modern age of technology, it does not necessarily mean new information. Starting from the stone, the punch card is now beyond the magnetic tape era, with all the latest data storage technologies such as hard disk drive or CD-DVD or USB drive.
But once thought, if ever the worst case of human history is lost, and all the papers are destroyed, all the technologies are damaged, they can not any information be stored in any way? His answer is hidden within DNA inside your body. The amount of data that is increasing in the world, once it is beyond the capacity of digital devices, protects against this problem, this data carrier or biodata storage in nature.
According to the scientists, future data storage is going to be DNA, which can be stored with more and more data in comparison to current devices. Not only that, all the data in the world can be stored in just a few grams of DNA. But how, and why DNA? And how much or how will it benefit? Is it possible to do theoretically possible? Let's move on to DNA world.
Before the start
Before knowing what DNA (Deoxyribonucleic Acid) will store data, let's take a look at what is in DNA and what happens on today's hard disk or other data storage devices?
We are all less familiar with diarrhoea DNA, which we are known as the container-carrier of sugar genetics. In a deeper sense, it can be found in its structural unit nucleotide and the long polymer of millions of nucleotides is a DNA molecule. DNA contains all the features of the human being. It does not only take place, but it also carries it into generations. And these features are information that is preserved in the four types of nucleotide nitrogen bases of DNA. These four nucleotide bases are Adenine, Guanine, Thymine and Cytosine. In short, we know the names A, G, T and C. More than 300 million nucleotides in a human cell.
In a previous article, I discussed how information on computer hardware is stored. The information is stored in the same way on all devices, only the type of work is different. The data is first converted to 0 and 1. Then, on the hard disk where they are stored, with the help of magnets, there is another device that uses electrons or photocopies.
But how will DNA hold this information?
Future hard disk DNA
In DNA, the nitrogen bases of each step form a pair of pairs, forming different types of formations. After a formula of DNA, the sequence of three nucleotide bays or special formatting is called 'Codon', such as AAA, AAG, ATG, and many more formats are possible. The nucleotide is a molecule of nitrogenous alkalis, one molecule Pentosh Schugger and one molecule phosphate compound. Each codon tells the amino acids or proteins to do something special. In other words, each code carries a signal and the proteins understand what they need to do.
When DNA carries signals it means that this feature of DNA can be used in a different way. Digital data means 0 and 1's game. So in any way, if this nucleotide sequence of DNA can be represented by 0 and 1, then it is possible to store digital data in DNA.

But how can this work be done? The idea is very common. Now work on 0 and 1 instead of letters or numbers. To say a little more clearly, Nucleotide A is released by 00, G is 01, T is 10 and C is 11 and all the binary codes can be stored in it, only if they are sequenced as necessary. In other words, nucleotide and binary 0, 1 complement each other in this process. And again, to read or use them, a DNA sequence decoder machine will be in compliance with the square algorithm. And synthetic DNA is made in the laboratory.
Earlier, in 1979, Harvard University's biologist Georges Church, at the time, spent $ 6,000 to purchase 10 nucleotides in order to store the data. So what does this technology seem to have recently discovered?
Although not recently discovered, it has been waiting decades to reach the advanced stage. And yet it is in the development phase. In 2009, Toronto researchers store images, text, and music files of a young child with a 200-by-bit thriller on a DNA strand.
In 2012, UK scientists were able to store 179 kilobytes of data in DNA and stored in Shakespeare's 154 sonnets and Martin Luther's 'I Have a Dream' lecture text files.
But until now, Microsoft has made the biggest record and the University of Washington researchers They were able to store 200 MB of data in 2016. And there was 'Universal Recognition of Human Rights' and the high definition 'Ok Gay' music video. But what will be the data stored in such a small amount? And what is the maximum amount can be stored in this DNA?
Capacities and prolongation
There are many limitations in the technologies used to store data so far. However, theoretically, one-gram DNA can store 215 petabytes of data. Another petabyte = 10,00,000 GB And 100 million HD movies can be stored in a pencil eraser. Currently, the amount of data that is currently being stored will go beyond the capacity of all the data storage devices used by the world around 2040. According to one of the 2016 data, the total amount of data on the Internet in the world is 1.1 zettabytes. And by 2020 it can cross 40-kilometre bytes. 1 zettabyte = 1 × 10 ^ 12 gigabytes. It is estimated that by 2025, this amount will exceed 163 debates. And this time DNA technology can come in handy. If that technology gets the fullness of those days.
On the other hand, only a few villages DNA can capture the information of the whole world, where a hard disk takes only a few terabytes of data to store a lot of space.
The two biggest successes of DNA storage technology are the accuracy and prolonged accuracy of information. All the data that has been stored so far has been accurately decoded and the error amount was zero per cent. And as long as there is lifespan, DNA will remain safe. Able to stay in cold and dry places for more than thousand years without light and air. Where a hard drive is effective only for a few years or for a decade. Apart from the possibility of hacking digital devices, there is a possibility of losing data for technical limitations. But there is no mutation in the DNA, but there is no fear of data corruption. That's why DNA is going to fulfil your 16th round of all aspects.
Not only that, scientists have tested the bacterium on its DNA sequence, and it survived in the void and it was also good to have radiation enough to kill people. And 1,000 times without reproduction, no data has been distorted.
Limitations and Chances
Apparently, the task seems to be very simple but it is involved in many complex procedures and calculations. So far, DNA sequencing is a very costly and time-consuming affair. DNA creation, sequencing algorithm and decoding it are still beyond the power of all. The technology that can easily be used by everyone is not yet available. Only limited to laboratories. Initially, scientists started with a few bytes but now it has reached megabytes.
Another problem is that to find a specific data, the entire DNA needs to be decoded.
But scientists are working for this technology. DNA sequencing has created new possibilities and next-generation DNA sequencing has many advanced branches like. Once upon a time, this technology will reach everyone and your hands will remain in the firmament of the whole world. Maybe there will be information that will keep you in the back of the garden and behind the trees in your garden, your family, country, or all aspects of life, pictures will have many fun moments or important information or history. Or perhaps a time the villagers will come and study them with DNA, discovering the human civilization of the past.
