Genes are the blueprints of life.
Genetic material found within cells determines the differences between all living organisms - plants, animals, humans and microorganisms. Genetic engineering is the process by which scientists artificially alter this information. It is accomplished by introducing selected genes into the host DNA without knowing precisely where they will end up. Given the complexity of DNA material, most of which is still unknown to us, this procedure has the potential to cause unexpected problems which could be passed on to future generations. Genetic engineering combines genes from completely different species.
