Comments Off on RNAs Techniques

The Acid Desoxirribonucleico, (DNA or ADN, as some literatures use) is a organic made up constituted of two ribbons of nucleotdeos that contains all the information necessary to co-ordinate the development and functioning of all the beings livings creature (and some viruses). The DNA has as main function the storage of the information necessary to construct proteins and RNAs. Until the beginning of the decade of 70, the DNA was a difficult made up very of being analyzed. For having a great extensive sequncia of nucleotdeos and ' ' repetio' ' chemistry the DNA was generally analyzed for indirect ways. New technologies had been developed throughout the decade of 70, allowing the isolation, the purificao and the study of specific genes in a known process as Clonagem Gnica. Many of the discovered techniques are fruits of the Microbiology, Imunologia, Biochemist and Microbiana Genetics and, the practical discovery and of these techniques had allowed that the DNA analysis had a new approach. technology of the recombinant DNA (currently called also Genetic Engineering), is a set of techniques of ample application, that allows to study, to analyze, to identify, to isolate and to multiply genes of any organisms, being one of the used sets of techniques more in the Biotechnology. Through it we can study mechanisms of response and gnica expression, to develop cultures of procariotos capable to produce substances extremely useful as, for example, the insulina or to determine the sequncia of a gene (and for consequncia the protein that it codifies). The application of these techniques has biotechnological, commercial and medicinal a potential inexhaustible. Currently, we can observe as benefits of the development of this technology (between that they exist): The identification of genetic illnesses, the production of agricultural insumos and the identification of kinship.
