RNA is thought to have a major role in life starting
SHUTSTERSTOCK / NOBASTESAFIERCE
The intention of understanding how the molecules of life progress is one step closer, according to researchers who make a system of rna molecules. They say it should be a day It is possible to achieve complete self-contempt for the first time.
RNA is a major molecule of coming in the origins of life, because two saving information such as DNA and Catalyze reactions such as Prasein. While it is not as effective as one of these, the fact that it can be identical to many researchers believe life begins with RNA molecules that can replicate themselves. “This is the molecule of running biology,” as James Actwater at the University College London.
But making the RNA molecules in RNA proved to be difficult. The RNA can form double helices such as DNA and can be copied in the same way, by dividing double helix to two and adding the RNA letters to each other equal helgic. The problem is that RNA Dougd Dough Helice will be united together that it is difficult to keep strands blind for a long time to allow the friction.
Today, water is found in water and the sets of three letters of RNA – triplets – full enough to prevent strands again. Three is sweet spot, as the water of withdrawal, as longer sets are likely to be wrong. So, in the team’s system, a RNA enzyme of double-helix form mixed with triplets.
The solution is made acidic and heated to 80 ° C (176 ° F) to separate Helix, allowing triplets to match. The solution was made alkaline and cooled to -7 ° C (19 ° F). While the water freezes, the remaining liquid becomes more concentrated and the enzyme of RNA can be active and joined with triplets, making a new strand.
So far, researchers have only made up to 30 letters in the 180-letter RNA enzyme, but they think that by improving the enzyme effectiveness, they can achieve complete replication.
Water attack says this “very simple molecular system” has some fascinating properties. One is the possible relationship between the letters of the Triplet RNA and the triplet code used to determine the order of proteins in today’s selfs. “There is a relationship between how biology used its copying and how biology is using RNA now,” he said.
What else, does the team find triplets that are likely to be involved in contempt are those who bind stronger. The first genetic code is thought to have this set of triplets – another interesting link.
Researchers think that kind of conditions need to drive in this process can be naturally occurring. As it requires water in the water, it is likely to happen to the ground, perhaps in some geothermal system.
“The ingredients can be found in the world today – the warm fountains of Iceland can have a mixture of PHS, including some acid as we use,” as the water of the attor.
“RNA nucleotide triplets serve very specific functional functions to interpret all cells,” as Zachary Adam At the University of Wisconsin-Madison. “This paper is interesting because it can point out a pure chemical paper – an unsorted function – for RNA triplets that may be served before a living cell.”
