A engenharia genética Genetic engineering
SĂŁo abordados os progressos havidos com as tĂ©cnicas de engenharia genĂ©tica, capazes de alterar o potencial genĂ©tico de um organismo, quer pela introdução, quer pela supressĂŁo de novos genes estruturais. SĂŁo mencionadas algumas das aplicações em geral e, em particular, possibilidades de uso no campo da medicina. É feita uma análise crĂtica dos benefĂcios e riscos envolvidos.<br>This paper deals with the progress made in genetic engineering techniques, capable of altering the genetic potential of an organism, either by the introduction or the suppression of new structural genes. Some of the general applications are described as are also, more particularly, their uses in the field of medicine. A critical analysis of the benefits and risks involved is also undertaken
