Answer to Question 1
A GMO is a genetically-modified organism and can be either a plant or animal. Genetic modification involves manipulating the genetic material of an organism to force it to produce different or altered proteins. Sometimes this is done by simply modifying the DNA that the organism has. Alterations in the genetic material (DNA) can influence the proteins a plant makes and ultimately affect the protein quality of foods that we make from the plant. Sometimes, DNA from another organism is inserted in the nucleus. In this way, a plant with one or more limiting amino acids can be enriched with those amino acids and, as a result, be transformed into a complete protein source.
