Forensic DNA Testing is so important in the legal field and has helped solved many crimes. Forensic DNA testing has made leaps and bounds in the last century, though it is still not an exact science, with enough DNA test samples available it is pretty accurate.
In the early part of the 20th century the only tools police investigators had to determine the evidence left at a crime screen was to dust for fingerprints. Of course once the criminals realized they could be identified in that way they made certain they wiped away their prints so nothing could be traced backed to them. Now, even though not every criminal is caught and placed behind bars a good number of them are apprehended based on DNA testing.
Forensic DNA testing requires the analysis of thirteen different specters often called loci. Different loci will be tested depending upon the actual DNA data extracted from the crime scene. This composite of DNA test samples is actually quite accurate in pin pointing the individual bearing that genetic composition. The result of the sampling is referred to as the individual's DNA footprint.
Forensic scientists use DNA testing for a number of jobs. The first reason of course is to identify a criminal from the evidence left behind, while another reason could be to determine the identification of a corpse who was murdered or a victim of a natural disaster such as an avalanche or drowning. Forensic DNA testing is used in paternity DNA testing, pregnancy and DNA testing for victims of rape.
