1 Biotechnology Review

2 What are 2 CONS about biotechnology?
Unpredictable side affect High prices Biological weapons Food allergens Unexpected environmental impacts

3 GMO’s are also called ________
Transgenic organisms

4 True or False: Labeling of genetically modified foods can best be described as voluntary

5 List 2 examples of transgenic PLANTS
Golden rice Round up ready corn/soybeans Venomous cabbage Banana vaccine

6 What animal was the first to be cloned?
A Sheep

7 When are stem cells extracted
5 days after zygote starts dividing

8 Human Genome Project (HGP)
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)

9 Fragments of DNA that has been cut with restriction enzymes & have unpaired nucleotides at the ends are called _____________ Sticky Ends

10 ______enzymes cut specific sequences of DNA

11 __________is the total DNA in the nucleus of each cell

12 _________DNA refers to the DNA from the two different organisms

13 What enzyme chemically links (bonds) DNA fragments together?
DNA Ligase

14 _______ is a DNA molecule used to carry a gene of interest from one organism to another

15 The process of rejoining cut fragments of DNA is called __________.
Gene splicing

16 A __________ is a small ring of DNA in a bacterium

17 When a "normal" gene is inserted into the genome to replace an "abnormal," disease-causing gene, this is called __________ Gene therapy

18 What are 2 PROS about biotechnology?
Environmentally friendly products Possible cures for diseases New vaccines & medicines Bigger livestock Disease resistant crops

19 What is the process of creating genetically IDENTICAL copies of DNA/organisms called?

20 _______ are cells used to generate virtually any type of specialized cell in the human body.
Stem cells

21 Genetically Modified Organisms (GMO)
______ are organisms with artificially altered DNA; also called transgenic organisms Genetically Modified Organisms (GMO)

22 What was the name of the first cloned organism?

23 How many restriction enzymes are needed to make recombinant DNA?

24 Genetically modified foods
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

25 _______ are organisms that contain functional recombinant DNA
Transgenic organisms

26 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

27 What are the 2 most commonly used vector?
Plasmids, Viruses

28 Provide an example of how humans have used selective breeding.
Dog Breeds Cat Breeds Horse Breeds

29 List 2 examples of transgenic ANIMALS
Glow fish Fast-Growing salmon Enviro-Pig Less Flatulent Cows

30 List a risk factor associated with gene therapy.
Unwanted immune response Targeting wrong cells Infection caused by viruses Cause tumors

31 True or False: The Food and Drug Administration has approved human gene therapy products for sale?

32 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

33 _____________ is the process by which desired traits of certain plants and animals are selected and passed on to their future generations. Selective Breeding
