ABSTRACT

With the development of Biotechnology, and through the use of genetic engineering, the manipulation and transfer of genes between living organisms from different species have been accomplished. These whole processes are carried out by means of several techniques that have importantly contributed to the development of mankind. However, in the peculiar case of biotechnological products, increasing the scientific rigor is required in order to guarantee the innocuousness and safety of these components used as foods, active principles of drugs, or bioproducts able to interact with the environment. The main technologies allowing the evaluation of the presence of genetically modified organisms (GMO) are based upon the assessment of recombinant DNA, or thed etection of the newly expressed protein, which, in turn, is the product of modifications made in the hosting genome. These controls have been increasing at the same rate as research has developed. However, in many cases the exponential growth observed in these areas has not paralleled the growth of biotechnological progress. Some of the main techniques and analytical methods used for detection of a genetically modified specimen (either animal or vegetable) are presented in this work, along with their benefits, applications, and limitations.
