2. SOME QUESTIONS
1) What is genetic modification?
2) What are GM Foods?
3) Why are food genetically modified?
4) How do we achieve genetic modifications?
5) What are the benefits of GM Foods?
6) Who makes sure they are safe?
7) Which companies own the GM market?
8) What are the possible risks associated with GM
Foods?

3. What is Genetic Modification or
Engineering?
The direct manipulation of an
organism’s genome using biotechnology
is known as genetic engineering.

4. What are Genetically
Modified(GM) foods?
Foods that contain an added gene sequence
Foods that have a deleted gene sequence
Animal products from animals fed GM feed
Products produced by GM organisms

5. Why are foods genetically
modified?
Genetic engineering offers a precise and
rapid method of altering organisms as
compared to traditional methods that
are slow and inaccurate

6. Common GM foods
• Vegetables
• Tomatoes
• Potatoes
• Rice
• Cheese
• Meat

7. How can DNA be moved from
one organism to other?
It’s quite simple
actually

8. .
•Find an organism with the
desired trait
•Isolate the gene sequence that
codes for that trait
•Insert the gene sequence into
genome of the plant or animal
cell
•Allow the genetically altered cell
to grow and propagate

9. .
A vector can be used to carry
the DNA.
It could be a pellet from a gene gun
Viruses and bacteria is also used to
carry genes

10. Benefits of GM Foods
• Easing of world hunger
• Development of crops that can be grown in
marginal soil
• Reduced strain on non-renewable
resources
• Development of drought resistant crops
• Development of salt tolerant crops
• Development of crops that make efficient use of
nitrogen and other nutrients

11. .
• Reduced use of pesticides and
herbicides
• Development of pest resistant crops
• Reduced herbicide use is good for environment and
reduces the cost for farmers

12. .
• Improved crop quality
• Development of frost resistant crops
• Development of disease resistant crops
• Development of flood resistant crops

13. .
• Improved nutritional quality
• Development of foods with specific nutritional
values

14. Who makes sure that GM Foods are
safe?
• Government agencies regulate GM
Foods

15. .
• GM Foods in The US are required to be
labeled only if the nutritional value is changed
or a new allergen is introduced

16. MAJOR PLAYERS IN THE GM MARKET
The Big 6 :-
1) Monsanto
2) Syngenta
3) Bayer
4) Dow
5) BASF
6) Dupont

17. Possible risks of GM Foods
• Insects might develop resistance to pesticide
producing GM Crops
• Herbicide-tolerant crops may cross pollinate
weeds, resulting in super weeds

18. .
• Certain gene products may be allergens, thus
causing harms to human health
• There may be unintentional harm to wildlife
and beneficial insects

19. CONCLUSIONS
Genetic modification is a highly controversial
subject, with many in its favor while many against
it.
It has its own benefits as well as drawbacks .
It needs to be refined and its drawbacks
eliminated.

20. .
The science was elucidated by the scientists
with a noble intension, but some seems to
have monopolized the market and misuse it.
We need to appreciate the science and move
GM foods in a forward direction.
