DNA technology in the criminal justice system
The first time DNA technology was used in the court of law was in England in 1996 to contribute to a rape case. Two girls were raped and strangled on two separate occasions in 1983 and 1996. The suspect admitted to the rape and murder of the first female, but not the second.

Independent testing on DNA fingerprints has found that unrelated individuals can match on up to 9 out of 13 common markers used for evidence testing quite commonly. Some individuals can even match on 10 common markers, despite being complete strangers to each other. 6.
How to compare fingerprints for matching?
To compare fingerprints for matching, specific points of comparison are logged, either by a visual examination or analytic software, to determine its accuracy. Although this process is fairly accurate, it is not as accurate as DNA fingerprinting.

This is because DNA is a very flexible and tough molecule which doesn’t denature that easily.
How much DNA sample is needed to map an individual?
Perhaps only about 100 mcg of sample will suffice to map an individual’s biological information. For instance, a splotch of saliva over a drinking straw should be more than sufficient for a particular DNA sampling. After taking the right amount of sample, the significant regions will be amplified.
Why is DNA used in crime scenes?
This can happen because extraneous DNA can likely dilute crime scenes in public places like phone booths or restrooms. Likewise, DNA of innocent individuals can be used purposely to be able to pass the blame. Hence, the reliability of results should depend greatly on the equipment, personnel and laboratory.
How to identify an individual?
This is the process of using a person’s DNA which is a unique biological map pointing to a particular person and his or her kin. Nowadays, this method has been widely utilized in law enforcement for solving crimes as well as identifying criminals. This can also be used to prove or disprove certain consanguinity claims.
Why do we need DNA fingerprints?
Because every organ or tissue of an individual contains the same DNA fingerprint, the U.S. armed services have just begun a program to collect DNA fingerprints from all personnel for use later, in case they are needed to identify casualties or persons missing in action . The DNA method will be far superior to the dogtags, dental records, and blood typing strategies currently in use.

When was RFLP fingerprinting first used?
RFLP fingerprinting was first used in 1987 in Scotland, and since then it has been used in thousands of court cases (Collins, 2002). RFLP fingerprinting analyzes the lengths of specific DNA bands excised from the main DNA molecule by cutting with restriction enzymes.
What are the advantages of PCR?
The main advantage of PCR is the ability to analyze small amounts of DNA by amplifying it (Figure 4) . However, due to its sensitivity, PCR fingerprinting is prone to possible contamination. The process of creating a PCR fingerprint consists of three major steps (Figure 5).
