__________. Vaccines for the H1N1 virus can be made from

_____. Ag biotech has developed a rapid diagnostic test to

help keep ________ healthy. Any 1 fact you learned from the video

HOW DOES BIOTECHNOLOGY AFFECT YOUR FOOD?

Food is considered to be safe if it spoils before pathogens become dangerous

What can you do to delay pathogen growth? Pasteurization Low temperature (refrigeration and freezing) Drying (removal of H2O)

GE MOVIE QUESTIONS A gene from a _______ was put inside of

tomatoes to make them freeze proof. Adding genes, like vit A can make foods

more _________. Gene therapy is when a _______ gene is

replaced with one that works properly. Leukemia and Parkinson's have been treated

using _________. Studies done in the 1980’s said that GM

food was _________.

HOW DOES BIOTECHNOLOGY AFFECT YOUR FOOD? irradiation (UV, x-ray, gamma radiation)

MODERN USES OF BIOTECHNOLOGY How is biotechnology used for good? To make mass quantities of medicine (penicillin,

insulin) (next slide)

Forensic testing (DNA in court cases) Bioremediation (removing pollution from

soil/water) Crime SceneSuspect 1 Suspect 2 Suspect 3Suspect 4

Scientists began to try to increase the amount of penicillin produced by P. C. bacteria, by irradiating it with X-rays and UV rays in order to induce mutations of this species. They succeeded and developed a mutant that produced 1000 times the amount of penicillin than Fleming’s original culture

HOW IS BIOTECHNOLOGY USED FOR GOOD? To make genetically modified food In 2008, New Zealand researchers developed

a tear-free onion through gene-silencing technology.

In 2008, American researchers developed a biotech carrot with 41 percent more calcium than conventional carrots.

GENETICALLY MODIFIED FOOD U.S. researchers announced the

production of genetically engineered cattle that cannot develop prion proteins, which can result in the degenerative disease bovine spongiform encephalopathy (BSE).

EOG PREP What makes fertilizers a benefit to the

farming industry? A They increase the nutrients in the soil B They increase the growth of helpful

bacteria C The decrease the chance of bacteria

growing in the soil D The decrease the chance of plants

being eaten by insects

EOG PREP Which is most likely responsible forthe formation of cancer cells?

A an antibiotic B a mutagen C a bacterium D a parasite

GM FOOD DEBATE Discover website – Home, April, Sidebar http://

discovermagazine.com/2013/april/16a-anti-gmo-efforts-us

1. What does GMO stand for? 2. Why are about 90 percent of the corn, soy,

and cotton grown in the U.S. genetically modified?

3. A handful of scientists speculate that genetically modified crops may be responsible for what in humans?

4. What has constantly spraying genetically modified crops with Roundup caused?

5. Write one 5 sentence paragraph arguing that GM foods should be allowed and one 5 sentence paragraph arguing that GM foods should be banned

EOG THOUGHTS Journal question: How do you feel about the EOG’s and

why. Do they make you nervous, excited, etc? How do you normally do on the tests, and what are some strategies for success that you can start putting into place now?
