Biotechnology Review
What are 2 CONS about biotechnology?
•Unpredictable side affect•High prices•Biological weapons•Food allergens•Unexpected environmental impacts
List 2 examples of transgenic PLANTS
•Golden rice•Round up ready corn/soybeans•Venomous cabbage•Banana vaccine
The mapping and sequencing of all the genes in the human genome that was
completed in 2003 is known as the ____
•Human Genome Project (HGP)
Fragments of DNA that has been cut with
restriction enzymes & have unpaired
nucleotides at the ends are called _____________
•Sticky Ends
When a "normal" gene is inserted into the genome to replace an "abnormal,"
disease-causing gene, this is called __________
•Gene therapy
What are 2 PROS about biotechnology?
•Environmentally friendly products•Possible cures for diseases•New vaccines & medicines•Bigger livestock•Disease resistant crops
_______ are cells used to generate virtually any
type of specialized cell in the human body.
•Stem cells
______ are organisms with artificially altered DNA; also called transgenic
organisms
•Genetically Modified Organisms (GMO)
Foods that contain an added gene sequence;
foods that have a deleted gene sequence; animal products from animals fed GM feed; products
produced by GM organisms are all
considered ___________ •Genetically modified foods
List 1 PRO about genetically modified
FOODS.• Reduced use of chemical pesticides• Less runoff of chemicals into waterways•Greater use of farming practices that prevent
soil erosion• Higher profits for farmers• Less fungal contamination•More nutritious foods• Easing of world hunger• Improved crop quality
List a risk factor associated with gene
therapy.
•Unwanted immune response•Targeting wrong cells•Infection caused by viruses•Cause tumors
True or False: The Food and Drug Administration
has approved human gene therapy products
for sale?
•FALSE
List 1 CON about genetically modified
FOODS.• Insects might develop resistance to
pesticide-producing GM crops•Herbicide-tolerant crops may cross-
pollinate weeds, resulting in “super weeds”•Soil is being saturated with toxins•Certain gene products may be allergens•Unintended harm to wildlife and beneficial
insects
