More recently is the expert that lawyers rely heavily on the relationship with the analysis of evidence of forensic scientists to make DNA profiles, fingerprints, or is capable of.

DNA profiles

Forensic scientists can do DNA analysis to identify the 0.1% difference between human DNA to determine whether the DNA material found at the crime scene match those of defendants. This process has been very welland was also used to resolve cases of the past and succeeded, in some cases, a few prisoners who have declared their innocence of the crime were to relieve trapped in the past.

Process

The process of DNA profiling is a process by which DNA samples from the crime scene from various sources, collected, how the hair and skin cells. The DNA will be extracted from samples and the use of different enzymesThe recognition of patterns in DNA. DNA will be forced to call through a gel, which are separated by an electric current running through a process of electrophoresis. The fragments will be compared with other samples to determine whether there is a match. This process is very precise for the identification of substances in a crime scene DNA, but can not say whether the DNA material of someone, why the authorities have planted entirely trustDNA profiles.

In recent years, DNA analysis successfully with both lawyers and prosecutors to establish or challenge the accuracy of the tests. This is because it provides an accurate method for determining whether a suspect was found at a crime scene or the defendant's DNA on the victims, who find fault, especially in cases of rape. However, DNA analysis should not be the sole basis for determining the guilt, becausethe possibility of DNA material from the real perpetrators of a crime planted.
