Dna Database

When it comes to DNA, it is something that we all have within us. It contains cells and patterns unique to every individual, with an exception when it comes to identical twins. DNA is used by criminologist to help determine who has been present at the crime scene. There are many advantages to using DNA but there are also some disadvantages that must be evaluated.

The biggest advantage when it comes to DNA analysis is identification of a criminal suspect when they have committed a crime. Because everyone has their very own unique DNA, it is very rare for mistakes to happen. DNA test results are much clearer than doing fingerprints and DNA analysis is really important in cases of rape, because it allows medical personal to examine a victim and find traces of the a rapist's DNA. Since DNA laboratory sue a polymerase chain reaction is only requires a small amount to test, and now can be used in older cases when the DNA may have been more degraded.

Now DNA also has it disadvantages when it comes to an individual sense of privacy. DNA is a person genetic makeup and it reveals sensitive information about a person and must be handled with care. Most samples are also kept even when a suspect has been cleared off a crime and held for future use. Police try and use these sample for future crimes, which comes into to play weather the police had probable cause. Many Personal rights advocates have argue that keeping and storing DNA is unethical for many reasons. Eventhough DNA fingerprinting is very accurate, it also is very sensitive and can be contaminated very easily.
