The components of this new computer are altogether new – they are made of DNA. Deoxyribonucleic Acid (DNA) is a molecule with a genetic signature of all living creatures.
The DNA computer, first of its kind, can regenerate as it computes. That means, the performance of DNA computer would surpass any stretch of imaginations available as of today to scientists and engineers. The Manchester University researchers used a Universal Turing machine (UTM) to check the feasibility. Unfortunately, no quantum UTM is available as of now to find the reproduction factor. Even though Electronic computers are a derivative of a UTM, this particular computation failed.
The exponential speed these quantum computers can attain is available with the scientists for a long time, but putting that knowledge into practical use was elusive. But now it is proven to be a reality- possibility to create a UTM using DNA molecules physically.
It is like searching for a needle in a haystack or logically locating the shortest path within a maze. Electronic computers can find out this to absolute accuracy and speed. But the new DNA computer can regenerate, multiply and replicate at incredible speed rather than sticking to the conventional computational norms, that too at an astronomical speed!
Present computers are composed of silicon chips whereas new ones are composed of DNA. The limitation, in other words, is that the current day computers are having constant number of chips. The DNA computers can grow as per demands. Quantum computers have their own merits over conventional ones. It is like finding out a possible path in a maze using fuzzy logic, algorithm or chaos theory. (As per chaos theory, there is symmetry in every chaotic situation like a maze).
Now the super computers would be history once DNA computers are in the picture. DNA molecules are tiny and the space occupied is negligible. The speed of a DNA computer would be unimaginably higher. May be, new standards for Peta in speed are called for!
The biological molecules used in DNA computer and four alphabets are used to represent the data. They are A (adenine), G (guanine), C (cytosine) and T (thymine). The conventional binary alphabet, which is a series of 1s and 0s used by conventional computers, are now redundant. The discussion on DNA matching in forensic as well as the existing objects will soon cover computer as well.
Alan Turing, who was a huge part of the University in the 1940s, is considered to be the father of computer science. He created the first stored memory electronic computer known as Universal Turing machine (UTM). He was wartime code-breaker as well.
Manchester breakthrough is going to change the way in which we talk about the computer. The Computers made out of DNA molecules will be a reality rather than being just a far-fetched possibility. The Manchester University is famous for its connection with wartime code-breaker, Alan Turing.
Technically, this process is known as a Non-deterministic Universal Turing machine (NUTM) using “unlimited‘ DNA molecules.
