3. How does our understanding of genetics affect our lives?

9. Genetic engineering is making changes in the DNA code of a living organism.
Scientists can “cut and paste” DNA from different sources to get recombinant DNA.
A technique called bacterial transformation allows a cell to take in foreign DNA and incorporate it into its own.

10. Bacterial Transformation
Bacteria have circular DNA called a plasmid that can be exchanged easily between cells
STEPS:
1. Restriction enzymes cut DNA in specific places
2. A vector, or a virus, delivers the new gene into the bacteria
3. The new genes are inserted into the bacteria’s DNA
4. The bacteria begins to express proteins from the new genes

12. Transgenic Organisms +

13. Transgenic Organisms organisms that have DNA from another species
Bacteria can be engineered to produce insulin (enzyme needed to treat diabetes)
Plants can be engineered to be resistant to diseases and pests
Bacteria can be engineered to eat oil to clean up spills like the BP spill off of the gulf coast

14. GMO Genetically Modified Organism
The result of a laboratory process where genes from the DNA of one species are extracted and incorporated into the genes of an unrelated plant or animal

15. Dolly was created in a lab in 1997 from a single cell.
Cloning
Makes identical copies of an organism
The chromosome number of the new organism would be exactly identical to the old organism
All of the DNA, features and characteristics would be the same
Dolly was created in a lab in 1997 from a single cell.

16. Cloning Is cloning easy?
Not always successful and typically does not result in a healthy adult animal
Took 277 tries to make Dolly
Reason why human cloning is illegal in the USA
Many attempts would result in surrogate mothers experiencing miscarriages, stillbirths, or deformities in the baby

17. Newborn Genetic Testing
If you had a newborn child, would you get it tested for genetic disorders? Explain.
