1.Go to my wikipage : oconnorbiology.greenwich.wikispaces.net 2.Click on the Google Forms link 3.Answer the questions. 4.With the students in your row compare the resources you used. Rank in order which resources were the most reliable to the least reliable. 5.Be prepared to defend your ranking.
Selective Breeding It occurs between plants/animals of the same species (dog dog) Imprecise: breeder may not get the exact results they want right away (desired gene may not have been passed along) Takes a long time to get desired results Transgenic Engineering It can occur between different types of species (human bacteria) Precise: the desired gene is inserted into the organism Desired results can result much quicker
Humans selected for different characteristics of the Wild Mustard plant and eventually created many new types of vegetables.
Genetic Engineering: Processes and Hopes Read the New York Times Article: Growers Fret Over a New Apple That Won’t Turn Brown – The LEFT side of the class will highlight the PRO’s mentioned in this article – The RIGHT side of the class will highlight the CON’s mentioned in this article
#1. Risk of: pollen-pollution caused by cross pollination. Gene transfer to non-target species. Suggested Reasons AGAINST Genetically Modify Organisms
#1. Risk of: unintended harm to other plants and animals Suggested Reasons AGAINST Genetically Modify Organisms
#3. Reduced effectiveness of pesticides/insecticides or herbicides. Suggested Reasons AGAINST Genetically Modify Organisms
#4. Risk of: Unknown side effects for humans Suggested Reasons AGAINST Genetically Modify Organisms
#5. Risk of: economic concerns of monopolization Suggested Reasons AGAINST Genetically Modify Organisms
1. A plasmid (bacteria DNA) is removed from a bacteria cell. 2. DNA is removed from a human cell. 3. Using an enzyme, the desired gene (for insulin production) is isolated. 4. The bacteria plasmid is snipped open using an enzyme. 5. The human insulin gene fragment aligns binds with the opened plasmid. 6. The plasmid is inserted into a bacteria cell. 7. When the bacteria reproduces, the new bacteria cells will contain the human insulin gene. Human insulin will be produced and collected by scientists.
