How Can DNA Be Used As Evidence For A Crime?

DNA, or deoxyribonucleic acid, is incredibly powerful when it comes to forensic science. In some cases, it can serve as near-perfect evidence of a person's involvement in a criminal act. It can be found in a wide variety of places, including hair, saliva, semen, and blood. It can be used to support or refute a suspect's version of events or link the suspect to an unidentified suspect or victim.

How Can DNA Be Used As Evidence For A Crime?


On the technical side, DNA evidence is collected, typically at a crime scene, and then either tested in a laboratory or compared to databases of other samples. The comparison of DNA samples can then be used to determine if a suspect is linked to the crime or not.

 The accuracy of DNA evidence can vary, depending on its quality and if it was damaged or altered in any way. For example, DNA samples can be contaminated or misinterpreted, which can make it difficult to draw firm conclusions from the evidence. Nevertheless, DNA evidence is widely accepted in criminal investigations and can prove invaluable in certain cases.
