2. What is GM Food? GM food stands for Genetically Modified Food
Organisms are made up of cells containing genes, the hereditary material which is DNA (deoxyribonucleic acid) in nature
GM food is food with genes modified. Genes can be transplanted by taking out useful pieces of DNA from one organism and merging them with the DNA in another organism.

4. Why produce GM food? To improve the quality of food
To improve food production to feed the world
To strengthen the resistance against herb and pests
To cope better with climatic changes
To minimize the cost of production
To minimize loss during transport and storage

5. Herbicide Resistance
Herbicides, like glyphosate and glufosinate, are used to eliminate weeds to maintain nutrient content in the soil but they decrease the yield.
Scientists insert the herbicide resistance genes via agrobacterium into food plants so that they will not be affected by the herbicide.
This reduces the excessive use of herbicide.

6. Pest resistance
Scientists insert the toxin producing gene from Bacillus thuringienus, a kind of soil bacterium, into maize.
Destructive insects will be killed when eating the crop.
The loss due to destructive insects is greatly reduced.

9. Will GM food incur Health Problems?
GM food is consumed as DNA molecules.
As human body has been coping perfectly well with foreign DNA for millions years. No harm is proved at this moment.

10. Harmful to eco-system? Will it affect the growth of other plants?
Will living things lose their living environment?
Will it create strange species?

11. Any side-effects?
Will genes used to modify crops jump the species barrier?
Can the possible DNA mutation be controlled?

Will it repel choice of food?
