Genetic Engineering
Genetic engineering is a technique used by scientists to transform the DNA (deoxyribose nucleic acid) of living organisms. DNA is the blueprint for the individuality of an organism. The organism relies upon the information stored in its DNA for the group of every biochemical process. The life, growth and unique features of the organism depend on its DNA. The sections of DNA which have been associated with specific features or functions of an organism are called genes. Molecular biologists have discovered many enzymes which change the structure of DNA in living organisms. Some of these enzymes can cut and join strands of DNA. Using these enzymes, scientists learned to cut the specific genes from DNA and to build customized DNA using these genes. They also learned about vectors that are strands of DNA such as viruses, which can infect a cell and insert themselves into its DNA. Scientists soon began to construct vectors which inserted specific pre-chosen genes into the DNA of living organisms. The job of the Genetic Engineer today is to improve certain aspects of living organisms to prevent diseases or
