DNA Profiling

DNA Profiling

1. Process of making a pattern of bands from a person's DNA to compare with other DNA patterns

2. Uses no-coding DNA

3. 1. Extract DNA

   • 2. Restriction enzymes cut the DNA into fragments
     • 3. Gel electrophoresis is used to separate the fragments
       • 4. Copy of pattern saved onto x-ray film
         • 5. Pattern is analysed

4. Applications

   • Forensic Science
   • Paternity Testing
   • Pathogenic Strains
   • Genetic Archeology
   • Genetic Screening
     • Testing people to see if they have a specific gene
       • Used in screening for a genetic disorder
         • Down's Syndrome, Sickle Cell Anaemia, Cystic Fibrosis, hereditary cancers

5. Issues: Ethical

   • Who gets access to the profile
     • employers/insurance
