1. 13-4 Applications of Genetic Engineering
Questions to think about???
How are transgenic organisms made?
What are the mains steps in cloning?

2. Some Background Info…
We know that DNA from one organism can be inserted into another
Does that mean that gene works the same way in a different organism?
YES!!!
The gene for luciferase from a firefly was added to the DNA of a tobacco plant
The recombinant plants glow 

4. Transgenic Organisms Organisms that contain genes from other organisms
Genetic Engineering allows scientist to insert genes from one organism into another organisms cells. These cells can grow into new genetically “modified” organisms

6. Examples of Transgenic Organisms
Microorganisms
Transgenic bacteria
Make necessary human proteins like insulin and growth hormones
Animals
Used in scientific research & to increase food supply
Mice inserted with human genes to study immune response
Livestock have extra copies of growth hormone genes
Plants
Crops inserted with genes that produce insecticides
93% of soybeans and 88% of corn in the U.S. is G.M. (genetically modified)

7. Cloning
Clone-population of genetically identical cells made from 1 cell
1997 Ian Wilmut cloned a sheep
Nucleus of the egg is removed
Empty cell is fused with a cell from an adult
Fused cell is placed in the reproductive system of a foster mother
Hello Dolly!
