This technology was developed during
the 1970s to enable scientists to modify characteristics of living
organisms by precisely manipulating their genes. Genetic modification is possible because all living organisms use the same molecule - DNA - to store coded genetic instructions to regulate the cell. Genes, which contain the "recipe" for making proteins, are made up of segments of DNA. The same DNA sequence in two different organisms contains the code for the same protein, just as the opening notes of Beethoven's Fifth Symphony produce the same melody whether you play them on a violin or a trumpet. Like traditional breeding, genetic modification allows us to introduce changes in the characteristics of an animal or plant by making changes to the DNA. Genetic modification in plants involves seven basic steps:
