Finally! A computer DNA has been reset


DNA is said to be DNA to save us from computer computing. With the advancement of silicon use, DNA-based computers promise to make enormous composite computer architects impossible to access today.

But there is a problem: The molecule trips that have been built so far have no flexibility. Today, using DNA for digging, it's just how I have to remove a new computer from a new hardware just to run a new piece of software, ”said the user. T computer scientist David Doty. So Doty, professor at California, Davis, and his colleagues are trying to find out what it would be doing to restore the DNA DNA.

As explained in a paper published this week NatureDoty and his colleagues from Caltech University and Maynooth University looked directly at that. It showed its ability to use a simple movement to introduce the same basic set of DNA molecules to produce a number of different algae. While this research is still exploratory, there can be some reusable marine molluscs algae in the future to make DNA robots that have already successfully delivered drugs to cancer cells. .

“This is one of the area's notable papers,” said Thorsten-Lars Schmidt, professor of experimental biology at Kent State University who was not involved in the research. “There was an algal autonomy before, but not so complicated.”

In electronic computers such as the one you are using to read this article, two-fold units of information that tell your computer what you should do are extracts from your computer. . They represent the physical hardship of the hardship, usually from electrical attendance or away. These parts, or the electrical signals in action, are being channeled through guided walks of logic gates, which carry out work on one or more pieces of input and which carry one piece of work. as a result.

Combining these simple building blocks across and beyond, computers can offer the advanced programs. Their idea behind the DNA computing is to include chemical attachments for electronic features and nuclear devices for silicon to create bio-turbine software. According to Erik Winfree, a computer scientist at Caltech and the co-author of the paper, molecular algorithm boasts the ability to process natural information cleared of DNA, but instead of releasing the natural appearance t says, he says, “control the process of growth. ”

Over the past twenty years, several tests on molecular algorithm have been used to make things like a tick-tac-toe game or different shapes. In each of these cases the DNA sequences had to be carefully designed to create a single specific algorithm to generate the DNA structure. What is different in this case is that the researchers designed a system where all the basic pieces of DNA can be ordered in order to arrange for themselves without allergies to. completely different – and so, final products are completely different.

The process starts with DNA origami, a method of wrapping up a long piece of DNA into the form you want. This piece of paper wraps as the “seed” which proceeds to the algorithm line, similar to that of wire falling in sugar water as a siege when it was grow a rock candle. The seeds are still the same, regardless of its algorithm, with alterations made only to a few small lines within each new test.

Once the researchers have formed the seed, it is solved around a further 100 DNA strands, known as DNA tiles. These slabs, each made up of a special arrangement of 42 nucleobases (the four basic biological partners making DNA), are taken from a larger collection of 355 DNA tiles created. with the researchers. In order to create a different algorithm, the researchers would choose a different set of starting tiles. Thus a molecular algorithm that randomly rotates a different group of DNA tiles must be used to count algorithms. As these DNA strings connect to the course of the collection process, they circle a circle that selects the selected moilecular algorim on the pieces that the seeds are given.

Leading the use of this system allows the researchers to create a total of 21 algorithms which could include identification of multiples of three, choosing a director, moving patterns, and counting to 63. All these algorithms were sent Action using a combination of the same 355 DNA strings.

A writing code by throwing DNA slabs in a tube test the masts away from how easy to write on a keyboard, of course, but it represents a model for flexible DNA computers at a time. future. In fact, if Doty, Winfree, and Woods have a way, today's mollusc programmers don't have to think about the basic layouts of their programs, just like today's computer programs don't have to. understanding of the cross-media physics to write good software.

It was a very basic science, in this case, proof of a concept that produced beautiful fruit, even though it was useless. However, according to Petr Sulc, a professor at the Biodesign Institute of Arizona State University, who was not involved in the research, the development of repetitive molecular algorithms to open nanoscale assembly for doorway is possible for many complex applications. Sulc suggested that one way this day could be useful for creating nanoscale factories which collect peat compounds or powders for drug delivery. He added that he could also contribute to the development of nanophotonic materials so that the path could be created for light-based computers rather than electricity.

“With these microscopic algorithm types, one day we may be able to assemble any complex element on a nanoscale scale using an accessible general socket set, just as living cells can gather in cells. T A bone or neuron cell simply by choosing which proteins form it, "says Sulc.

The potential uses for this type of nanoscale will maintain its conservation, but these estimates are also based on our limited understanding of the hidden capabilities in the nanoscale world. . After all, Alan Turing and the other people involved in computer science could hardly make predictions on the Internet, so some of them may have. imperfect requests that they require for computer science waiting to be waiting.
