... , one might ask, "What is genetic engineering?" Genetic engineering (GE) is a laboratory technique used by scientists to change the DNA of living organisms. DNA is the blueprint for the individuality of an organism. Every organism relies upon the information stored in its DNA for the management of its biochemical processes. The life, growth, and unique features of the organism depend entirely on its ... DNA. DNA can also be broken down into smaller segments called genes. Genes are directly associated with specific features and/or functions of an organism ... scientists have started to b...
