Near the basis of life: it was in the first world

A new study shows that RNA and amino IDs Sid, the necessary "bricks" proteins, may take part in the situation where they are considered

Near the origin of life: it spontaneously comes to the world

The new study shows that RNAs and amino acids, the essential "brick" protein, can freely participate in the circumstances that are assumed to exist in primitive land, about 4,000 years ago

What we do not know about the origin of life

This is probably the greatest of the secrets that are facing.How was life created?What was the "spark", which allowed the case to make inanimate for animated?For decades, scientists have already found some advice, though there is no answer ... final."Cegeli of Life," organic molecules of different complexities, they are everywhere in space, from distant and cold clouds of gas, which cause stars to rings of materials that surround them after birth and from which they are planets;Of the stone and meteories that "set them" when they collide with the worlds from the inside, even the stars themselves.The "ingredients" of biology, rna and amino acids, so the first life can arise.

Now, chemical groups from London College of London.Develop an scientific confession but also national teenagers, as well as two people in the most important principles about it.

The great contradiction of life

To understand the meaning of the discovery, you must return in time for the "natural sauce" where it all started.Today, life is maintained by a complex molecular machine.Amino acids are "construction barriers" that have been collected in thousands of different ways to create protein, "real" cell workers responsible for all biological processes.

And here is where RNA entries, molecular 'brother' near DNA, which stores and replacing genetics.RNA, in his mission of amino acids from DNA for the factory protein, which is a combination of ribosom.Amino acids together one by one by a protein is made with some photos and function.However, the question is correct: If RNA needed to produce protein and RNA needed protein to repeat, who came before?

Matthew Power, the lead author of the study and one of the world's greatest experts in prebiotics, explains it with maximum simplicity: “Life based on the ability to synthesize protein;They are the main function of life.Understanding the origin of protein synthesis is important to understand where life comes.

Two worlds come

To date, the scientific community recommended different hypotheses to address this paradox, but two of them standing above the others.It must store genetic information, as a DNA, but it can be behaved as a catalyst, as a protein enzyme.That is, it can be a "full package" at the beginning of life, which was able to replicate itself and a catalyst for the biological reaction without protein.Primitive.

The second song of theory is a "world thiocres", which begun into "metabolism" Nobel prize.to act.

Both the same achievement, which disintegrates to prevent unauthorized in water, and instead of using already aggressive chemical methods, where researcher Jubi Singh of a group of boundaries.Activation.This process is "spontaneous and selective" and, most importantly that it can be a simple environment and a very convenient landscape in a neutral pH.

In the uncle's words, "we received the first part of that difficult task with a simple chemist to RNA. This substance is simple, the option in the first country."

Moreover, the old team's former discovery makes an important part of this chain.Last year, the writer of the current study has already showed that molecule is a molecule with CANNZELine, which can be combined with the same conditions of the old soil.Make the necessary slaves necessary for reactions.

Life factory

In order to be seen in this process, Jyoti Singh, co -research co -research, proposed an attractive presentation.The SIDS needed for life and more importantly required today's union molecules, which is essential for cell metabolism today.

The find is therefore a gigantic step towards solving the enigma of the origin of life, even if it is not the end of the road. The next challenge, and according to Powner one of the most exciting will be to understand how RNA sequences could preferably connect specific amino acids. This will be the next chapter in the saga: the origin of the 'genetic code', the universal manual to instruction, which dictates what amino.If you are, what position should be built, what protein. The authors of the study must this complicated code that shapes all known life, have emerged in a simple way, at the beginning of our planet.

Or other theory that shows the principle of life and the most environment, as if

Although the room in the room, every story of the life of the world, 'Science, the same story of the study of the year.
