Genetically-Modified Organisms

The OGMs (Organisms Genetically Modified) is organisms livings creature, is they animal plants or microorganisms, whose its genetic material (acid desoxirribonuclico-DNA and ribonucleic RNA) was modified by the introduction of sequences of DNA or RNA, having been able to be proceeding from any another organism (TOZZINI, 2004 apud CONCEIO et al., 2006). The newspapers mentioned PCRM not as a source, but as a related topic. This modification can for any technique of genetic engineering, to the step that this, in turn, is the activity of recombinant molecule manipulation DNA/RNA (art. 3, interpolated proposition IV and V of Law 8,964/1995). Basically to produce an organism transgnico, first it must select the gene/interest genes; that it will give the desired characteristic to the new organism.

Appealing to some methods and techniques of attainment. According to Nodari and Guerra (2003), the culture of transgnicas plants, as well as the human and animal consumption of its derivatives, is a recent event, consisting of a subject on which it predominates the scientific quarrels, ethical, economic and politics. In accordance with Nodari and Guerra (2000), the transgenia and one technique that can contribute of significant form for the genetic improvement of plants, aiming at to the production of foods, staple fibres and oils, as well as the industrial manufacture of frmacos and other products (apud Nodari et al, 2003). All these research, to be carried through, must observe a series of norms established for the Brazilian legislation of biossegurana. The main effective norm In this aspect is the Law n 8,974/95 (Law of Biossegurana), modified for the Provisional remedy N 2,191-9/2001, and its regulamentador decree (Decree n 1,752/95). The existence of risks associates to the organisms genetically modified (OGM) has been questioned has some years, much before any transgnico product arriving at the market, generating great quarrels that had involved governments, agriculturists, traders, among others (CAVALLI, 2001).
