2. Determine Family Relationships
DNA fingerprinting- patterns of bands seen on the gel electrophoresis.
Unique to each individual
Used to:
Solve crimes
Unsolved mysteries
Determine Family Relationships

3. Gel Electrophoresis It is used to separate DNA Fragments
The gel used has small pores

4. 1. Restriction Enzymes cut DNA into small fragments
2. DNA fragments are then poured into wells on the gel

5. 3. An electric current is hooked up to the gel, and moves the DNA across the gel
4. DNA is slightly negative and will move towards the positive pole
5. The smallest pieces will move the fastest

6. 6. A dye is added, and the result will be bands of DNA

7. Medicine Cures found in DNA codes Genetic techniques developed:
Gene therapy
Improve and develop vaccines
Diagnose disorders

8. Gene Therapy Fastest growing areas in genetic engineering
Gene therapy- the changing of genes that cause a genetic disorder or controlling the symptoms of a disorder.
Example: cystic fibrosis
