Genetic Engineering Webquest


I.

Gene Therapy


A.

How do scien
tists use viruses to insert a “good” gene into
someone with a genetic disease (like “Bubble Boy
Disease”)?








II.


“A Gene You Won’t Forget”



A.

Under what conditions do fruit flies develop l
ong
-
term memory?



B.

What does this tell you about how you can improve your own memory or study better
for a test?



C.

What did the genetic engineer do to the fruit flies to improve their memory?




D.

If this was available for you to do for your child would you
do it?





III.


“Wisdom of the Worm


A.

What are nematodes?



B.

What is this biologist studying in these worms?




C.

How did she change the DNA of the worms?




D.

What happened to most of the worms she
did this to?




IV.


Gene Doping


A.

What do they use as a “vehicle” to carry the gene with new instructions into an athlete’s
cells?



B.

What does this cause to happen in the athletes’ bodies?




C.

What are

some of the negative consequences of this type of gene doping?





D.

Do you think there is a big difference between “gene therapy” and “gene doping”?





V.

GE Salmon


A.

What did you learn about gen
etically engineered salmon?







VI.

Browse GM Foods


A.

What are 3 things that they are changing in rice by using genetic engineering?





B.

What are 3 things that they are changing in th
e ingredients on a pizza?






C.

How are geneticists reducing the population of pest insects on farms?






D.

Describe one

more genetically engineered food on the table that you might eat one day?


VII.

Create A Bt Tomato Plant


A.

What are you trying to alter (change) in the tomato plant?


B.

What does Bt (Bacillus thuringiensis) produce that can be beneficial to tomato plants?



C.

Why would you want to insert this gene into the tomato plants genome?




D.

Summarize each step you would take to genetically modify the tomato plant:



Step 1:



Step 2:



Step 3: (Notice how quickly bacteria can divide)



Step 4:



Step 5:



Step 6: Herbicide is sprayed onto the plant cuttings to kill off any cells tha
t do not have

the herbicide
-
resistant gene in them. This is a separate gene from the insect resistant

gene that we originally got from the Bt bacterium.



Step 7:



Step 8:


E.

What kinds of ethical questions could arise from this genetically modified or
ganism?






F.

Would you want to eat a tomato that has been genetically modified?
