Genetically Modified foods – A Definition
Genetically Modified foods (GM foods) are produced from Genetically
Modified Organisms (GMOs). GMOs have specific changes made to their DNA
by genetic engineering.
How does it work?
Genetically Modified Organisms are organisms in which the DNA is altered so that
it allows selected individual genes to be transferred from one organism to another.

Why is Genetically Modified food needed
When crops are attacked by
insects and pests, the crops
get destroyed. Genetically
Modified foods are resistant to
insects, pests and different
weather conditions. They can
even live in extreme weather
conditions.
