·         Genetic engineering, sometimes called genetic modification, is the process of altering the DNA? in an organism’s genome?.

·         This may mean changing one base pair? (A-T or C-G), deleting a whole region of DNA, or introducing an additional copy of a gene?.

·         It may also mean extracting DNA from another organism’s genome and combining it with the DNA of that individual.

·         Genetic engineering is used by scientists to enhance or modify the characteristics of an individual organism.

·         Genetic engineering can be applied to any organism, from a virus? to a sheep.

·         For example, genetic engineering can be used to produce plants that have a higher nutritional value or can tolerate exposure to herbicides.
