Genetically engineered seedlings. View of a pipette dropping nutrient fluid onto genetically engineered seedlings. The seedlings are being grown in petri dishes in a protective environment. The aim of the genetic engineering is to alter the plant's DNA (deoxyribonucleic acid) and thus change the genetic code of the plant. This will alter the plant's characteristics. The beneficial effects of this include protection against cold, parasites and diseases, as well as ensuring that there is a good harvest. It can also make the crop more resistant to spoilage after it has been harvested. In the background are volumetric flasks.
