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

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

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

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

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

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
