Scientists play a minimum tic-tac-toe game using a DNA game board – Technology News, Firstpost


The future of nanotechnology stands today, and it could be at the mercy of a small double-tape game played by researchers at the California Institute of Technology (Caltech).

In a test-for-concept for DNA origami, Caltech researchers used a new technique to create small structures out of DNA strands, and then play a tic-tac-toe game using a DNA board, because why not?

The origami DNA technique uses a natural tendency of centers (units) of DNA to continue with each other. Of the four centers in DNA – Adenine (A), Guanine (G), Thymine (T) and Cytosine (C) – A and T always go hand in hand, so C and G.

In the body, all of our DNA are prepared with these games – a sequence DNA string with GATCAATC, for example, will perfectly prepare the CTAGTTAG sequence on an "supporting" line Another DNA. Researchers are repossessed on this property from DNA to make shapes by treating the sequences of letters in it.

Although this is usually the case, there are also times when part of a DNA string can be prepared with each other. Draw a 3-way zipper where each single zip is taken half way down, and its two free arms can continue with different performers themselves.

Caltech tried to explain this mechanism using the passe dating correspondence, with graphs of one string dumping another string but only 5 of 8 corresponding bases for another string that make a better game, where 6 o to 8 base corresponds.

The "stand stand" together with the DNA origami technique was described in a published paper this week is Nature Communication, where researchers create tunnels in the form of a square of DNA that fits in a network, such as a pos.

In their display, researchers gave 9 empty tiles of DNA into a test tube, and after the tiles were collected tidy on the basis, the team went around one after adding Xs and If i & The tube. The tiles X and O that were added to the tube were simple simple games for the base bases or empty tiles.

After a 6-day game, researcher X appeared as the winner of this small game of X and O.

DNA formats may change many future applications, including drug supplying and molecule cargo, both of which are already being investigated and functional.

Unlike previous techniques where the structures have locked up after they have been created, the Caltech team could reconfigure the existing DNA board using the new method this.

"When you have flat tires, you're likely to replace it instead of buying a new car. Such a handbag can not be repaired for nanoscale machines," said Grigory Tikhomirov , one of Caltech's researcher news release.

"But with this tile displacement process found, it is possible to reset and upgrade multiple parts of engineering nanoscale machines that make it more efficient and sophisticated."
