GMO FOOD & ANIMALS

Page 7: Genetically Modified Organisms Foods

Definitions

• Agar- is a polymer made up of subunits of the sugar galactose, and is a component of the cell walls of several species of red algae that are usually harvested in eastern Asia and California.

• GMO- Genetically Modified Organisms • GRAS- Generally Recognized As Safe

• R&R- Round-up ready

Page 8: Genetically Modified Organisms Foods

Definitions

• Pathogen: An agent of disease. A disease producer. The term pathogen most commonly is used to refer to infectious organisms.

• Patho- means a disease.

• Gen- indicating a producer

• Genome- is a set of genes in a organism. The genes that you want to change.

• FDA- Food and Drug Administration.

Page 9: Genetically Modified Organisms Foods

Technology

• The new gene insertions are called transgenic or genetically modified organisms.

• The methods to this is through; transformation, injection, viral infection, or bombardment.

• Through DNA-coated tungsten or gold particles.• The two ways to do this is through a gene gun

(particle gun) or through bacterial vectors.

Page 10: Genetically Modified Organisms Foods

Gene Gun (Particle Gun) You have a bullet that is plastic,

containing the DNA pellets (containing the desired gene) of gold or tungsten particles

As it enters the cell at high speeds it leaves behind some of the DNA coating.

The pellets can travel at speeds around 1000ft/s

Page 11: Genetically Modified Organisms Foods

Bombardment

Is inserting into the cell similar to the Gene gun. Is also use to insert into living animal organs.

Page 12: Genetically Modified Organisms Foods

Transformation

• Same as Bombardment. • Transformation has three steps

• Arguably- leads to one or a few copies of engineered DNA to the plants genome. Keep the DNA intact.

• This causes tumors and galls this is where they insert the wanted gene.

• The Gene Gun• Protoplasts a cell gone through enzyme treatment to

get rid of its cell wall made by sugar polymers. • The plant as to be able to go through homologous

recombination. Some mosses can go through this.

Viral Infection Or known as viral carrierIt creates a virus and if infects a targeted

area.So the virus attacks the cell and replicates

this is when you add your selected gene in. GM DNA is 2-4 % different than the DNA of

the parent, this is due to unpredicted mutations.

Scientist took a human gene but in a single cell and the cell changed 5% of their expression.

GMO FOODS

Advantages

• Greater product yield• Could perhaps be

produced in larger amounts for less money through cloning

• Increased taste, colour, aesthetic appeal

• Easier for farmers to manage, and therefore grow for less

Disadvantages • World does not have a

food shortage, the world is just greedy

• Eventual adaptations and possible mutations of viruses and weeds

• Loss of natural elements, procedure, products

• Uncontrollable technology, replicates itself in nature

Page 15: Genetically Modified Organisms Foods

Resistance to pests

New viruses/weeds, which will increase development in

technology. Increases understanding of how the

body functions

Genetic pollution, cannot be contained by a fence, it

spreads through pollination

When problems occur they will be hard to stop, because

of the nature technology. I.e. The plants make more

than one copy of the viruses/weeds

Advantages Disadvantages

GMO FOODS

Page 16: Genetically Modified Organisms Foods

GM PLANTS• Do not need a permit if they meet these 6 areas

1. The plant is not a noxious weed

2. The genetic stuff introduced to it is safely placed into the plant’s own genome

3. The introduction is known and does not cause plant disease

Page 17: Genetically Modified Organisms Foods

GM PLANTS 4. GM plant is not toxic to non-targeted organisms

5. The gene will not cause new plant viruses

6. GM plant cannot contain genetic material from animal or human pathogens

Page 18: Genetically Modified Organisms Foods

Possible Actions Advantages More Jobs More foods Making under

developed countries slowly becoming more developed

Better nutrients in food

DisadvantagesSoil is damagedLoose wildlifeKill certain insects

like butterflies

Page 19: Genetically Modified Organisms Foods

Possible Actions Advantages Less pollutionLess environmental

problems Waste less time and

money Good For ethanol

fuel

Disadvantages Create pollination

pollution

Page 20: Genetically Modified Organisms Foods

Personal implications

Increase of income of certain farmers especially farmers that are powerful and bigger than usual family farms

But it can descended family farms losing your right to know about foods of today and have no right to choice between normal or GMO foods (which means no labels of products)

Page 21: Genetically Modified Organisms Foods

Personal Implications

It can cause diseases, cancers, birth defects, disorders and even developing defects as growing and aging which eventually killing people you care about or even yourself.

Thanks to GMO foods

we are losing our own

naïve plants and animals like cattle, corn, grains and other

foods that are not GMOPossible crime rates

for more money and

power in under developing countries

Page 23: Genetically Modified Organisms Foods

*Global Implications

*It can grow in just about everywhere in the world including drought areas and flooded areas as well.

*Getting people to be working as a more decent wage rate and can make the poor people like Kenya and other third world countries to have more nutritional and delicious foods for them.

Page 24: Genetically Modified Organisms Foods

*Global Implications

*Can cause illnesses and big companies want more. And people will have to work even when ill.

Interesting fact What seed did canola originate from?

Rapeseed Canola wheat

Which country came up with canola?

France

Canada

Brazil

Page 30: Genetically Modified Organisms Foods

Interesting Fact What was the main purpose of canola? Get rid of fatty acids to make it better to eat. What was other purpose of canola? Animal feed it is high in protein. Who is the biggest single producer of canola?

Canada United States Argentina

Page 31: Genetically Modified Organisms Foods

Interesting fact How much canola will be produced by 2015 in Canada ? 15 million tons 20 million tons 5 million tons

Page 32: Genetically Modified Organisms Foods

Interesting fact What can canola with stand? Canola can with standing herbicides. What was the main purpose of canola? Get rid of fatty acids to make it better to eat.
