How does GM work?

The first step in GM is identifying a gene for a particular characteristic such as herbicide resistance.

The gene, which may come from any other organism, is inserted into the DNA of a plant cell, giving it that trait.

This means, for example, that a field can be sprayed with weedkiller and the GM crops will be unaffected.

Plants can also be modified for pest resistance and for bigger yields.
