Once forensic scientists obtain a sample, they extract the DNA from cells in bodily fluids or tissues and copy it. They then separate the copied markers using a process known as capillary electrophoresis. This enables them to identify distinct markers and the number of repeats for different markers in each allele.

What does the police do with your DNA?

When the police test DNA that is collected at a crime scene, it creates a profile of where the individual genes are located in the DNA. The DNA profile obtained from the crime scene can be compared to DNA samples of any known suspects.
