Genetic engineering is a group of techniques that are being employed to change the genetic makeup of cells and move genes across the boundary of species to supply new organisms. There are a variety of techniques for moving genes by artificial means into recipient organisms. These methods include using chemical or electrical treatments to facilitate direct DNA uptake by the host cells; microinjecting of genes directly into host cells; firing tiny metal particles covered with the genes of interest into host cells (bioballistics); and using plasmids found in bacteria. Advantages and disadvantages exist for genetic engineering. Some advantages include produce new foods, tackling and defeating diseases and getting rid of illnesses in young and unborn children. Some of the disadvantages are may lead to genetic defects and limits genetic diversity. Genetic Engineering is one of the most controversial topics of this century. It might work miraculously but who knows the consequences of playing with the nature.
