DNA testing

 

Various developments in genetic research and molecular biology have led to the advent of DNA testing. DNA testing has several implications; however it is widely used in the identification of suspects of a crime.

 
Hair, blood, skin, fingernails or any other human matter that is left at the scene of a crime can be analyzed using DNA testing the results of which can be compared against further DNA testing to identify the genetic finger print of a suspect. As DNA is highly specific a positive match from this type of DNA will usual indicate that the person was present at the scene of the crime, although there are exceptions and there have been instances where DNA testing has been flawed. The results of DNA testing can the be used in court of law. An additional application of DNA testing is identification between two people who may or may not be related. DNA testing can show whether or not two people are related through analysis of their genetic makeup, and this method is often used to attempt to discover who the father of a child is if there is a possibility it could one of several people. However, this form of DNA testing is not flawless and results shown by this cannot be taken as one hundred percent accurate as there have been instances in the past where mistakes have been made, however results from DNA testing definitely can show who is most likely to be the father of a child with a relatively high degree of accuracy.
