1. Genetic Engineering

2. Warm-Up Questions
What does the phrase “genetic engineering” mean to you?
How has your life, or society as a whole, been impacted by genetic engineering?

3. “The Genetics is Right”
Which product does not contain GM ingredients?

8. Current GM Food Products
Soybeans
Corn
Cotton
canola
Rice
Bananas
Fish
Fruit trees

10. History of Food Technology
8000 B.C. end of nomadic era, agriculture begins
1800 B.C. people use microorganisms (yeast) to create food
A.D metal and glass packaging invented
1856 Pasteurization invented
1865 Genes and traits identified
1914 Quick frozen foods invented
1922 Hybrid corn achieved by cross-breeding
1953 DNA discovered
1973 Genes transferred from one organism to another
1990 US gov’t approves 1st
biotechnology product
Mid 1990s commercialization of biotechnology products

11. Genetic Engineering What is the genetic material? DNA
The code that defines life

17. Genetic Engineering Definition
Changing the genetic makeup of cells by introducing or eliminating specific genes using molecular biology techniques.
Also known as biotechnology

18. Why would we do it? Can change properties in a positive way
Grow higher
Grow faster
Pest resistant
More nutritious
Sweeter taste

19. So What’s the Catch? Positive changes can have negative effects too
Some may be tolerable
Some may be devastating
