What is DNA profiling used for in forensic investigations?

DNA profiling is primarily used in forensic investigations to analyze an individual's genetic material in order to identify or exclude them as a suspect in a crime. This technique allows forensic scientists to create a DNA profile based on biological samples collected from the scene of a crime, such as blood, hair, or saliva. By comparing the DNA profiles from the samples to a database or to those of potential suspects, investigators can determine whether there is a match or not. This process is crucial in establishing connections between a suspect and the crime, thus aiding in criminal investigations and the legal process.

The use of DNA profiling extends beyond simply determining if a suspect is connected to a crime; it also serves to exonerate individuals wrongfully accused. This reliability and specificity make it a powerful tool in modern forensic science, providing clear and compelling evidence that can withstand scrutiny in court.
