I. What is a Genetically Modified Organism (GMO)?
*Is any organism that has acquired one or more ________by artificial means. genes *A GMO is said to be___________. *This means that the GMO contains DNA from different species. transgenic

II. What are the benefits to genetically modify plants and animals?
To make pesticide ___________plants. GM plants can produce natural _________ 3) To increase ____________content. 4) To make food last ____________ 5) Getting food to the market __________ resistant pesticides. vitamin longer. faster.
4
III. Some Examples of GMOs:
a. Golden Rice is genetically _________so it contains _______ from daffodils to ________ the production of beta-carotene (an important precursor of Vitamin A). modified genes increase
5
b. Sweet Corn- Scientists
have also genetically ________ sweet corn so it contains ________ from a bacteria that allow the corn to produce a natural ____________. modified genes pesticide
6
**It is more difficult to genetically modify
c. Fish-These two salmon are the same age, but the GM salmon grew at about twice the rate. **It is more difficult to genetically modify animals than plants.

IV. What are the risks of GMOs?
1) Increase in food _______ The creation of new _____________ 3) Reduced ___________ content. 4) Create antibiotic ______________ toxicity. allergens. nutritional resistance.
8
V. What is Gene Therapy? *When a gene is missing or not functioning, a __________can result. disease Gene therapy is a way of putting the _______ gene back into our cells. correct
9
VI. How is it done? *Vector- carries the new gene to the BODY cells.
10
*Will this individual produce offspring with the normal gene?
No, because the sex cells were not altered.
