ORGANISMS

Page 2: GENETICALLY  MODIFIED ORGANISMS

What does it mean? Its genetic material (DNA or

RNA) has been changed by genetic engineering

Cannot occur in nature or in usual crossbreeding

Micro-organisms, insect, plants, mammals

Page 3: GENETICALLY  MODIFIED ORGANISMS

Division Haphazard

mutagens and ionizing radiation

wheat, canola,..no regulations by law

Conscioustransgenesis (Gene from other

kind of organism is used)

Page 4: GENETICALLY  MODIFIED ORGANISMS

Plants To make them more resistant

against pests or weeds To grow faster or bigger To be more nutrtious To create vaccines or other

medications

Page 5: GENETICALLY  MODIFIED ORGANISMS

Animals To create pets To research human diseases To produce products intended

for human therapeutic use (pharmaceutical products or tissue for implantation)

To produce industrial or consumer products

Page 6: GENETICALLY  MODIFIED ORGANISMS

GMOs & World 90% of GM plants originate from

the USA (50%), Argentina, Brazil or Canada

Page 7: GENETICALLY  MODIFIED ORGANISMS

GMOs & EU All of the countries banned or

significantly reduced GMOs EU authorized 31 modifications

(cotton 6, corn 17, soya 3,..) If some product contain GMO

(more than 0,9%), it has to be stated on the packaging

Page 8: GENETICALLY  MODIFIED ORGANISMS

Why yes? Use in medicine and research Eliminate famine Better resistance to weeds,

pests and diseases Foods with better texture, flavor

and nutritional value

San Joaquin Valley California, USA Important agricultural area Huge increase of soil salinity→

some crops can’t grow there→ use genes of salt tolerant species (mangrove) to make the crops grow there again

Desert?!

Page 10: GENETICALLY  MODIFIED ORGANISMS

Why not? Created just for a short period of

time→ we can´t really say if it is harmful or not

May affect biodiversity Food allergies Antibiotic resistance Is it humane at all?

The Schwarzeneggers of cows

Belgian Blue Mutation in a protein which

stops growing muscles Breeding for meat
