In criminal cases, this generally involves obtaining samples from crime-scene evidence and a suspect, extracting the DNA, and analyzing it for the presence of a set of specific DNA regions (markers).
Scientists find the markers in a DNA sample by designing small pieces of DNA (probes) that will each seek out and bind to a complementary DNA sequence in the sample. A series of probes bound to a DNA sample creates a distinctive pattern for an individual. Forensic scientists compare these DNA profiles to determine whether the suspect’s sample matches the evidence sample. A marker by itself usually is not unique to an individual; if, however, two DNA samples are alike at four or five regions, odds are great that the samples are from the same person.
If the sample profiles don’t match, the person did not contribute the DNA at the crime scene.
Any physical evidence left at the crime scene that can be tested to prove that the suspect was or was not present. This includes…hair,skin, blood, and any body fluids. These test are 98.999999 accurate.
DNA makes up who you are- you are the only person with your DNA and a copy of it is in every cell in your body- all you need is a hair to see who someone is- get the picture?
