DNA Profiling

DNA fingerprint testing was created by Alec Jeffreys. It was invented by Alec in 1985 and DNA determines who you are and what kind of blood samples you have inside of you. DNA determines on your genes inside of you it also can verify who your parents are also. It can also tell if you have a record or not it was created to help judges,cops,scientist,etc. Cops uses DNA reseach for theft,robberies,crime,evidence, criminal reactions, and for a killing scenes.DNA fingerprinting is a test to identify and evaluate the genetic information.It is called a fingerprint because it is very unlikely that any two people would have exactly the same DNA information, in the same way that it is very unlikely that any two people would have exactly the same physical fingerprint.The test is used to determine whether a family relationship exist between two people, to identify organisms causing a disease, and to solve crimes. Here are the steps from another site for DNA fingerprint testing: For a criminal investigation, photos of the criminal and suspect DNA are compared. The results in this case indicate that the suspect is not the criminal.
 * All of the DNA is broken into pieces at certain locations. This is done by chemicals (enzymes) that break each DNA strand at the same place.
 * The DNA pieces are placed at the top of a special gel held in a frame.
 * An electric current is applied to the gel. The current separates the DNA into bands of identical pieces. This process is called electrophoresis.
 * The band pattern is transferred to a nylon membrane containing a radioactive chemical. The chemical makes the bands show up clearly.
