DNA fingerprinting, also known as DNA profiling or DNA typing, is the technique used to compare the DNA samples of the suspect and the victim. This technique involves extracting and purifying the DNA from the samples, then using a method like PCR to amplify specific regions of the DNA. The amplified DNA fragments are separated using gel electrophoresis and visualized using a dye or other detection method. The resulting pattern of DNA fragments, known as a DNA profile, can be compared between the suspect and victim samples to determine if there is a match. DNA fingerprinting is a common tool used in forensic analysis to link a suspect to a crime scene or victim, or to exclude an innocent person from suspicion.
