According to Sun Fengjie, a professor of crop sciences at the University of Illinois and Sun Fengjie, a postdoctoral researcher at the University of Illinois, they found that some of the early stages of evolutionary history were preserved in the structure of intracellular ribonucleic acid (tRNA) molecules. And the most important information. The related papers were published in the new issue of the Journal of the Public Science Library and Computational Biology.
Among the many ribonucleic acids that have been discovered so far, the transfer of ribonucleic acid is the most direct medium between genes and proteins. Like many other ribonucleic acids, the transfer of RNA helps translate genes into amino acid chains that make up proteins. With the help of specific enzymes, each transfer ribonucleic molecule recognizes and binds to a specific amino acid, and transports the amino acid into the system of synthetic proteins. In order to successfully add the carried amino acid to the end of a growing protein, the transfer ribonuclease must also accurately read the coding segment of the messenger RNA, and the messenger RNA gives instructions for the exact order of the amino acids of the protein.
Tano-Anoris discovered that the structural properties of the transferred RNA may provide new information on how organisms and viruses evolved, and then began research on the transfer of RNA. He believes that the transfer of RNA is a very important fact in the task of building a protein, and it may mean that it appeared very early.
All the transferred RNAs self-assemble into a shape. If they are flattened, they will develop into a shape similar to that of a loquat leaf. The research group led by Tarno-Anorris started by looking for patterns in this type of temporal lobe structure, using detailed data on hundreds of molecules that represent the three kingdoms of viruses and organisms: archaea, bacteria, and true. Nuclear organisms.
Researchers have translated all the features of each transferred RNA lobe structure into coding symbols. This process allows computers to search for the most "simple" transfer RNA "family genealogy." They also performed the same analysis on each of the transboundary ribonucleotides to clarify the division of these subgroups throughout the "family tree." This comparison allows them to determine the order of differentiation of the virus and every superworld.
In the past, the leading group of Tarno-Anorris analyzed the broad classification of protein folding and suggested that archaea was the first to emerge with evolutionary discernable features. The new analysis completed this time supports past research conclusions. Archaea is a microorganism that can survive in boiling acid, near sulfur-bearing volcanic vents or other extreme environments.
Tano-Anoris said that the new analysis also showed that the virus appeared shortly after the appearance of archaea, and that eukaryotes and bacteria appeared at a later time in turn. This finding may affect the current debate about whether the virus exists before or after the cells appear. He said: "This finding supports the theory that the virus originated in the cell domain."
All of the transferred RNAs self-assemble into a shape. If they are crushed, they will look like a lobe. The patterns of these structures provide clues to the early evolutionary history.
