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.
