DNA Fingerprinting

 

DNA research has improved our ability to link criminal and paternity information to individuals.  

  1. Forensic Uses

    In criminal cases, blood, tissue, hair or skin cells may be left at the crime scene. The DNA gathered from these sources are then compared to DNA of possible suspects. If the DNA matches then it is used as evidence in their court case, proving that they are guilty. In rape cases semen can also be used as sources of DNA evidence.  The DNA is then later compared with the criminal suspects' DNA fingerprints to determine who committed the rape.

  2.  Paternity Uses

DNA is hereditary and is passed from a parent to a child. Also, with DNA testing, the identification of a parent can be determined by comparing the child's DNA with the parents.  More and more, paternity cases are being determined using DNA testing.  http://resources.emb.gov.hk/biology/english/inherit/dna_finger.html
