Genetic engineering involves changing the genetic make up of an organism.
Genes are 'cut out' of the chromosomes of an organism using an enzyme. The genes are then placed in the chromosome of another organism.
The genes may be placed in an organism of the same species so that it has 'disired ' characteristics or in a different species. For example, the gene to produce insulin in humans can be placed in bacteria so that they produce insulin.
Many people agrue about whether or not genetic engineering is right. Will it create new organisms that we know nothing about? Is it going aganist nature?
