Genetic profiling~

• Everyone's DNA is different as they have different order of base pairs and different bases.
• The only people that have the same DNA are identical twins.
• DNA profiling use the DNA bands to identify specific individuals.
• Genetic profiling is also known as DNA profiling.
• This process is done by cutting out a piece of DNA into short pieces (fragments) by using an enzyme and separating the fragments by size into bands.
• DNA is cut up with an enzyme.
• The fragments are separated into bands.
• 3 things that genetic profiling can determine:

  -The paternity of a child.

  -To catch a criminal.

  -Genetic disorders.
• A genetic disorder that can be identified by using genetic profiling is cystic fibrosis.
• This results in finding the illness and treating it before it gets any worse.
• Things that can be left at a crime scene that contains DNA are:

  -hair

  -nails

  -blood
• Paternity means who the father is.
• To determine the paternity of a baby, you must already know the DNA of the mother.
• All the bands in the baby's DNA must match up to both the mother and the father.
• 4 advantages of genetic profiling:

  -DNA evidence is reliable.

  -Can be used to determine the father of a baby.

  -Identify genetic disorders early.

  -Used to place suspects at a crime scene.
• 4 disadvantages of genetic profiling:

  -Used by insurance, loan companies or 'employers' to refuse you insurance or job.

  -Storage of DNA can be seen as an invasion of privacy.

  -Theft of DNA profiles.

  -Possible to plant DNA at a crime scene.
• The UK has the biggest DNA data base in the world.
• The type of people in the data base are criminals.
