How Genetic Engineering Works
Identification of a Gene
Replication of desired Gene (or artificial creation)
Separation from DNA strand
Addition to other strand

Why is the rice golden
Genes from daffodils make beta carotene
Patented in 1999
Not yet in farmers hands
Reaction to Golden Rice
Some say it goes against God’s plan

These arguments have been reformed and are used
to describe GMO’s in general.
Some Think GMO’s are Bad

No Reduction in Chemicals
Focus somewhere else
Others Defend GMO’s

No negative health effects
Reduced pesticides and tilling
Solution to the patent problem
What other possible negatives could there be?
What other positives could there be?

Does it bother you that you may have eaten
genetically modified food without knowing?
Any other thoughts about GM foods?
The Current Reality of GMO’s
Genetically modified foods are in production.
There are more than just GM foods.
These foods are in production and it appears as
though only more are coming.
