Studies have shown that the thickening agent or the early life of the key factors that help to complete the self reproduction is generally believed that the earliest forms of life are based on rna. Georgia Institute of Technology researchers Kristen Ho (right) and Professor Martha grove. Sina Technology News Beijing on October 14th news, according to foreign media reports, according to the original theory of the universe, the origin of life in the ocean or pond. The theory holds that life is the product of a variety of factors, such as rainfall, mixed molecules, the warmth of the sun and cool at night. Recently, scientists at the Georgia Institute of Technology, published the latest research results, the formation of the prescription of life should also include a key factor – thickening agent. The formation of life must rely on the so-called thickener, thickening agent to help similar genetic chain of things for the first time in the sea or pool of self replication. It is generally believed that the earliest forms of life are based on rna. The theory suggests that, in the course of a long evolutionary process, the self replicating RNA chain grows to be long enough to form a gene, which marks the beginning of life. The long chain of nucleotides may and nucleotide short chain mixed pond, in the sun under the effect of heat, the longer the nucleotide chain from helix interruption and pairing and nucleotide chain is short, the final copy of the form. However, in the pure water environment, when the temperature drops down, the nucleotide long chain will quickly return to their spiral structure, there is almost no time to complete the pairing procedure. This is called "chain inhibition". The United States Georgia Institute of Technology scientist Kristen and Isaac – galego et al. Hope to be able to solve a mystery, the enzyme appeared before the early form of modern gene encoding is how to achieve the first copy. The researchers did not choose the experimental environment in the water. They add a viscous solvent, a thickener, to the "soup", which contains the real gene chain, to slow down the speed of the long chain. Kristen explains, "it looks more like the chemistry of the origin of life, because there may be a lot of sticky pools on the earth before the origin of life. In such a solution, a short chain of fast motion has the opportunity to jump onto a long chain and form a long chain of replicas." Figure a shows that the replication process cannot continue in a water environment. Figure a shows that the viscous thickener allows the gene chain to be paired with a possible copy of the component. In the experiment, the researchers’ ideas not only proved feasible, but also achieved exciting results. A strand of DNA and RNA chain folded together, forming a hairpin shape, which contributes to the RNA and DNA to complete the matching process. In addition, this shape also allows for more possible functional activities, such as the role of ribozymes. Kristen explained, "if the ribozyme can promote gene encoding replication in the same process, it is possible to accelerate the formation of the earliest life." In order to demonstrate the importance of viscous thickeners in the original soup, the researchers used the相关的主题文章:
