Though Adleman’s approach was seminal, his algorithm was not expressed within a formal model of computation. This is the moment when DNA computing is born. Adleman eliminates the wrong molecules through chemical reactions, which leaves behind only the flight paths that connect all cities. Within a few seconds, all of the possible combinations of DNA stands, which represent answers, are created in the test tube. A chain of these strands represents a possible answer. These molecules are then mixed in a test tube, with some of these DNA strands sticking together. some sequence of these four letters represented each city and possible flight path. Genetic coding is represented by the letters A, T, C and G. Adleman used strands of DNA to represent cities. As you add more cities to the problem, the problem becomes more difficult. The goal of the problem is to find the shortest route between a number of cities, going through each city only once. ![]() In fact DNA is very similar to a computer hard drive in how it stores permanent information about your genes.Īdleman uses DNA to solve a well-known mathematical problem, called the directed Hamilton Path problem, also known as the “traveling salesman” problem. Adleman, a computer scientist at the University of Southern California, came to the conclusion that DNA had computational potential. In 1994, Leonard Adleman introduced the idea of using DNA to solve complex mathematical problems. The technology is still in development, and didn’t even exist as a concept a decade ago. DNA computers can’t be found at your local electronics store yet. Lets first have a look at the starting point of DNA computing. After this experiment, interest in DNA computing has increased dramatically, and it is now a well-established area of research. ![]() Although its theoretical history dates back to the late 1950s, the concept of computing with molecules was only physically realized in 1994, when Leonard Adleman demonstrated in the laboratory the solution of a small instance of a well-known problem in combinatorics using standard tools of molecular biology. It is relative to many other fields such as chemistry, computer science, molecular biology, physics and mathematics. DNA computing is a new field of science that considering biological molecules as basic components of computing devices.
