Bodies of all living beings consist of proteinaceous structures which carry out a set of functions. For example, the muscles allowing to move to our bodies are under construction of the proteins which are formed with the participation of RNA as a result of biosynthesis. And as scientists claim, from RNA of polymers life on our planet began.The sponsor of placement P&G Articles on the subject "What Is RNA" How to determine reaction temperature That such collapse That such nervous fabric Ribonucleic acid is a polymer which consists of the nukleozidfosfatny elements united among themselves by fosfodiefirny communications. The macromolecular structure of RNA generally has an appearance of a one-filar chain which in turn can form two-spiral sites. This acid plays an important role in the course of activity of all live organisms, participating in synthesis of proteins and formation of genetic material.
On television and in other mass media often speak about DNA and the related opening, but thus seldom mention ribonucleic acid. And by the way, the interesting fact is that on the earth there are organisms which do not bear in themselves DNA a code, and contain only RNA. And, according to some scientists, the first live organisms were formed of this structure. Thus it is important to note that the RNA various types in cages of bacteria, plants and animals carry out different roles.
Formation of RNA happens in cages, to be exact, in a cellular kernel. Under the influence of polymerases of enzymes which catalyze formation of nucleinic acids, on a matrix of deoxyribonucleic acid there is a process of biosynthesis of Ribonucleic acids. At viruses this process happens on RNA-dependent RNA polymerases.
Information RNA – this type of ribonucleic acids, has the biggest length of a chain, among the others. I-RNK plays a role of a carrier of hereditary information cage cytoplasm from its kernel.
Transport RNA – participates in process of synthesis of protein and is engaged in delivery of amino acids to ribosomes. This RNA type, as well as previous, settles down in a kernel and cytoplasm of a cage and has the most smaller length – 75 nucleotides. But, despite the small length of a chain, t-RNK has the most difficult structure.
Ribosomalny RNA – this type contains in kernels and ribosomes of cages. The main function of this RNA type, broadcasting, a catalysis and formation of communications between amino acids and t-RNK is.
