Once amplified, the DNA fragments are separated by size using a process called electrophoresis. The Process and Technology Behind the Analysis Modern DNA analysis relies on a technique called Polymerase Chain Reaction (PCR), which allows scientists to make millions of copies of specific DNA segments.
Future DNA Technology Identification Methods and Their Applications
Authorities compare DNA from unidentified remains with samples provided by family members, such as a toothbrush or hairbrush. It is used in organ transplantation to find compatible donors by comparing genetic markers.
Identifying Victims in Disasters When traditional identification methods fail, such as in plane crashes, fires, or large-scale disasters, DNA fingerprinting becomes crucial. Investigators compare DNA found at a scene—such as in bloodstains, hair, or saliva on a cigarette—with a suspect's genetic profile.

These are short sequences of DNA that repeat next to each other, and the number of repeats varies significantly from person to person. This process allows for the accurate identification of victims, bringing closure to grieving families and aiding in the official documentation of casualties.
