Objective: Understand the Applications of Genetic Engineering New Words: Transgenic Organisms, GMO (Genetically Modified Organisms)

Genetic engineering is a technique that makes it possible to transfer DNA sequences from one organism to another 1. What is genetic engineering? 2. What are transgenic organisms? Organisms that contain genes from other species Examples of Transgenic organisms Transgenic microorganisms Transgenic plants Transgenic animals Objective: Understand the Applications of Genetic Engineering New Words: Transgenic Organisms, GMO (Genetically Modified Organisms)

They reproduce rapidly and are easy to grow 3. Why to use transgenic bacteria? Production of insulin, growth hormone, and clotting factor 4. How do humans benefit from transgenic microorganisms? Transgenic microorganisms Production of Substances to fight cancer Plastics Synthetic fibers 5. What do we expect to achieve in the future? Objective: Understand the Applications of Genetic Engineering New Words: Transgenic Organisms, GMO (Genetically Modified Organisms)

How to Transform Bacteria? 4. The recombinant plasmid replicates and a large number of identical bacteria are cloned. They produce human insulin. 2. Remove a plasmid from a bacterium and treated with the same restriction enzymes. 3. Bind the plasmid with the human gene to form a recombinant plasmid. Then the recombinant plasmid is re-inserted back into the bacterium 1. Remove the DNA from a human body cell, then isolate the human gene of insulin using restriction enzymes. Objective: Understand How to Transform Bacteria New Words: Transgenic Organisms, GMO (Genetically Modified Organisms)

7. How do humans benefit from transgenic plants? Increase crop productivity Corps able to resist weed-killing chemicals Crops that produce a natural insecticide, not need to spray pesticides 6. What are transgenic plants? Plants that contain genes from other species Transgenic Plants Transgenic Corn Objective: Understand the Applications of Genetic Engineering New Words: Transgenic Organisms, GMO (Genetically Modified Organisms)

Golden rice is a variety of rice produce through genetic engineering to include vitamin in the edible parts of rice. Golden rice was developed as a fortified food to be used in areas where there is a shortage of dietary vitamin A. No variety is currently available for human consumption. Although golden rice was developed as a humanitarian tool, it has met with significant opposition from environmental and anti-globalization activists Genetically Modified Organism (GMO) Golden Rice Objective: Understand the Applications of Genetic Engineering New Words: Transgenic Organisms, GMO (Genetically Modified Organisms)

8. What are transgenic animals? Animals that contain genes from other species 9. How do humans benefit? Increase meat productivity Livestock with extra copies of growth hormone genes to grow faster and produce leaner meat Transgenic chickens resistant to bacterial infections Transgenic Animals Objective: Understand the Applications of Genetic Engineering New Words: Transgenic Organisms, GMO (Genetically Modified Organisms) 10. What do we expect to achieve in the future from transgenic animals?
