Biologists have taught bacteria to synthesize proteins from amino acids, since no terrestrial organism has yet been used for this element. Thus they opened access to humanity for a large number of people who could be benefited from, for example. like lky.
In the famous Cambridge University laboratories, dark China bacteria grow تنمو Escherichia coli, which do not respect the basic rules of functioning of terrestrial organisms. The bacterial strain, named Syn61-3, is an alien species. It produces protein molecules like our planet has never seen before. In addition, the microbe uses its family information in such a way that it completely protects it from infection with any virus. American synthetic biologist Abhishek Chatterjee of Boston College stated that the emergence of Syn61-3 bacteria was a real breakthrough.
It opened the way to the production of inexhaustible quantities of entirely new books, and Chatterjee commented on the prospects for practical use of the discovery published in scientific journals. Science.
Vechny pozemsk formi ivota, bacteria coli bacteria Without exception, they have family information stored in a DNA double helix. The instructions for producing protein molecules are written in different letters of the genetic code. The combination of three consecutive letters is an order that the beech includes one amino acid in the protein. Proteins are made of hundreds of amino acids and are formed in a DNA double helix with a sequence of several thousand letters of the genetic code.
The three letters of the genetic code can be combined into different triplets. These three act as a signal for the end of protein synthesis, that is, as a kind of flow at the end of the sentence. However, the remaining three will be able to make proteins from six different amino acids, and sell hundreds of them. The earthly life for them, of course, used only two tablets, and only their addition gave them three.
Ddin info up to its extravagant PLTV ability. For example, the amino acid beech serine enters a protein molecule by order of an ester of three different letters of the genetic code. To complete the synthesis of a protein molecule of amino acids, he made three different twins. Jason Chen and his colleagues decided to hide these hidden reserves of genes.
Two years ago, the Jason China team produced bacterial information in the lab coli bacteria Formed by those and pl of millions of dogs of genetic code. Since the DNA contained in beech bacteria of this species was sold, its structural appearance differed in eighteen thousand cities. As a result of genetic corrections, the bacteria did not have the usual sense of the three different letters of the genetic code for incorporating the amino acid serine into proteins, and only had to deal with them. I drank one of the stop orders.
Chen and his colleagues kept the orders and kept them in reserve for experiments. Bacteria do not mind. In synthetically prepared DNA, spare orders were found at pslunch sites. Thus the amino acid serine continued to reach all the first cities of protein molecules. Where the chips were to be produced, it continued, because this was replaced by another gene flow.
After that, the scientists got rid of the bacteria and the lessons, which ensured the reaction to the directed trio. Syn61-3 bacteria not only miss your genetic commands, but if someone gets information in them, they won’t be able to respond to it.
immunity to you
And so the bacteria acquired a sudden resistance to germs. These viruses kill the bacteria in the beech microbes with the information of their family and force the involuntary host to produce new viruses according to them. However, the Ddin information virus also contains the three letters of the genetic code that Jason Chin and colleagues removed from the Syn61-3 bacterium.
If Syn61-3 bacteria are attacked by a phage, they do not go away. When, according to the foundations of DNA viruses, the microbe is able to produce its proteins for the phage, the necessary serine molecules cannot be introduced into it, and therefore if it does not complete the synthesis of these proteins. Bacteria arising from Syn61-3 infectious bacteria causes a major malfunction that renders it nonfunctional. Syn61-3 is immune to them.
Virus resistance wasn’t the only property Jason Chen added to Syn61-3 bacteria. In a new experiment, he prepared the central bacterium, which, according to his instructions, included the formation of amino acid molecules in the resulting protein molecule that had not yet been used by the terrestrial organism.
Next, the scientists gave an order to one of the bacteria’s Syn61-3 genes and immediately waited for the microbe to take on the challenge. The bacteria complied with the instructions given and produced according to n a protein containing three exotic amino acids in selected cities.
The researchers thus pushed the Syn61-3 bacterium to form an etzc sloench entirely of exotic amino acids. Then the rings formed rings of molecules. The molecules of some antibiotics or chemotherapies associated with malignancies have a similar shape.
The cyclic particles produced by Syn61-3 bacteria do not contain pollen cells. This was not the point of the research. The main benefit of the study is that it showed the difference in the spectrum of amino acids to produce proteins with the help of bacteria such as Relin.
