What’s A DNA computer? Can It Overcome on The World’s Fastest Supercomputers?


The idea of DNA computing was introduced in 1994. It deals with the “biochips” made of DNA that’s actually able to execute billions of calculations at the same time by multiplying themselves in amount. As it computes, to put it differently, a DNA computer grows. In a current development, the researchers from the University of Manchester have proven that the creation of this conceptual computer is potential in actual life.

Intel is fighting to boost the speed of their CPUs because of the limitations of Moore’s law. One other chip manufacturers are also working hard to win against the speed records. There’s no denying the truth that scientists and research workers should look for silicon choices for faster computing. The silicon-based computers have a limited quantity of central processing units and, consequently, their capabilities can also be finite.

Here, I’m going to let you know about one such concept–which might appear magical’ that is ‘ to you

 What’s a DNA computer? How can it work?


Back in 1994, the concept of computing with DNA was suggested to create computations faster even with a little footprint. It’s important to highlight was the power to multiply itself and execute numerous calculations simultaneously. By making multiple duplicates of itself put simply, unlike an ordinary computer that performs computations one after another, a DNA computer does those calculations at once.

The trouble geared toward finding the shortest route between a number of cities out by going through each city only once.

In his experiment, 7 cities were signified by the strands of DNA. The sequences of genetic alphabets A, T, C, and G symbolized cities and also the route. Next, when the DNA molecules were blended in a test tube, some DNA strands stuck together and the chains of fibrils were the solutions that were potential. Using some chemical reactions, incorrect molecules were removed. You can also read more regarding the process in detail in this paper composed by Adleman himself.


These DNA molecules can store billions of times more information as compared to tradition storage devices. Also, a DNA computer will undoubtedly be environment-friendly and compact in size.

What’s the latest progress? Is DNA computing planning to be a reality very shortly?


In 1997, basic DNA logic gates, which was viewed as a breakthrough were developed by the researchers at the University of Rochester. Lately, a major development in the area of DNA computing was made by the researchers from the University of Manchester, which is well-known for creating first stored memory electronic computer.

The researchers have shown that it’s potential to construct a DNA computer as it’ll computer, that’ll grow. This notion is also being called a nondeterministic universal Turing machine (NUTM).

As the DNA molecules are very tiny, a desktop “DNA” computer can utilize more chips than all the electronic computers in the world joined. Consequently And “ outperform the world’s current fastest supercomputer, while using up a tiny fraction of its energy,” according to Professor King of Manchester’s School of Computer Science.

This layout uses the DNA’s ability to replicate to execute an exponential number of paths. Their paper reveals this layout works using in vitro molecular biology experimentation and computation modeling. You’ll be able to also read the research paper to know more details.

Currently, the area of DNA computing is in its own nascent phase, and it’ll take quite a while to create a working DNA computer. But, whatever might function as the speed of progress, the notion absolutely sounds exciting.
