Gene technology involves the modification of deoxyribonucleic acid (DNA), the chemical that
makes up the genetic code of living things. The use of gene technology to produce a
genetically modified organism may involve:
* eliminating a gene,
* altering a gene,
* adding extra copies of an existing gene, or
* adding a gene from another organism.

The new or altered genes change the way in which cells function and so, change the
characteristics of the organism. When DNA from an organism is modified using gene technology,
the organism is then referred to as a genetically modified organism. The DNA on its own
isn’t.
