Genetically modified crops. Genetically modified crops (GM crops, or biotech crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques. In most cases the aim is to introduce a new trait to the plant which does not occur naturally in the species.
OVERVIEW OF THE TECHNOLOGY. Genetically modified organisms (GMOs), organisms in which genes from another organism are inserted into the targeted organismâs DNA, have the potential to both positively and negatively affect the environment and human health.ffects on the environment are a particular concern with regard to GMO crops and food production. One area of development involves adding the ability to produce pesticides and resistance to specific herbicides.
