Recombinant DNA: its functions and moral differences Genetic engineering has been revolutionised by a new technique known as recombinant DNA, or gene splicing, with which scientists can directly alter genetic material. In recombinant DNA, the DNA of one organism is joined with the DNA of a second organism to produce a recombined DNA. When this recombined DNA is introduced into another organism it permanently changes the genetic makeup of that organism. Specific genes and their DNA determine an organism's characteristics through the formation of specific proteins such as enzymes and hormones. Proteins perform vital functions: or example, enzymes initiate many of the chemical reactions that take place within an organism, and hormones regulate various processes such as growth, metabolism and reproduction. Recombinant DNA technology essentially alters the characteristics of an organism by changing its protein makeup. Recombinant DNA techniques have transformed genetic engineering in plants and animal food production, industry and...
