What is genetic engineering?

Genetic engineering, also called genetic modification, refers to a new set of molecular techniques. With these techniques, scientists are able to take DNA from any species – bacteria, viruses, insects, animals or even humans, and engineer them into another organism. An example would be selecting a gene, which leads to the production of a chemical with antifreeze properties from an arctic fish, and splicing it into a potato or strawberry in an attempt to make it frost-resistant.
