The DNA fingerprinting process is called gel electrophoresis. It is a process that can sort pieces of DNA according to its size. The process is done by taking samples of DNA from the crime scene and comparing it with samples from the accused. Samples are taken from biological materials like blood, semen, hair, and saliva. In the testing process the DNA samples are first entered into the wells in a gel like substance called Agarose. The gel is placed between two electrodes, one negatively charged and the other positively charged. The wells in the Agarose are inserted on the negative side because DNA has a negative charge. Molecules of DNA then travel in lanes toward the positive side. Small molecules will travel farther than the bigger ones, because they have an easier time moving through the gel. So the molecules wil

Boggan, Steven In The Courts: Girl Found Body Of Murdered Mother Hidden Inside Electronic Library, January 14, 1998

In Narborough, England two high school girls at the age of fifteen were raped and killed. A seventeen-year-old boy, Rodney Buckland turned himself in for one of the murders, in 1986. His DNA sample didn't match the semen found in the girls bodies. So he was the first person in history to be cleared of a crime by DNA fingerprinting. After Rodney was cleared, they started a DNA based manhunt. Every man in that area between the ages of 18 and 35 was asked to turn in their blood samples voluntarily. A conversation discussing this matter between Colin Pitchfork and his friends was over heard by someone in a local pub. They were discussing how a friend was going to turn in a blood sample for him so he would not get caught. The police were called and Colin was arrested. His blood sample matched the one from the crime scenes. He was sentenced to two life sentences, in 1987. He was the first murderer to be convicted by a DNA fingerprint.

l then be assorted according to their size. Next, the gel is X-rayed to see the parallel bands (showed by black bars on the film) in each lane. The separated molecules of DNA form a pattern of parallel bands that show the structure of the DNA. The pattern should never change for one person. In a court of law, the results of a DNA fingerprinting examination can be used to convict or acquit an accused person. If the accused's DNA matches the one at the crime scene then that person could be convicted.
