Genetic engineering is the direct treatment of an organism’s genome using biotechnology. It is a set of technologies used to alter the genetic makeup of cells, together with the transport of genes within and across species boundaries to produce improved organisms. An example would be to protect plant from insect damage, it can be made into a transgenic plant. Transgenic plant are called genetically modified organisms (GMO) because there is a gene added or removed in the original plant to obtain a set of characteristic such as insect damage.
