Therefore, it is possible that a fingerprint 22 weeks after conception could be used to identify a 50-year-old criminal . DNA fingerprinting, also called DNA typing, DNA profiling, genetic fingerprinting, genotyping, or identity testing, in genetics, method of isolating and identifying variable elements within the base-pair sequence of DNA (deoxyribonucleic acid). DNA can be used to identify criminals with incredible accuracy when biological evidence exists. Yet, until the computerization of fingerprint records, there was no practical way of identifying a suspect solely on the basis of latent fingerprints left at a crime scene, because police would not know which set of prints on file (if any) might match those left by the suspect. Image caption: In DNA fingerprinting, scientists collect samples of DNA from different sources — for example, from a hair left behind at the crime scene and from the blood of victims and suspects. They then narrow in on the stretches of repetitive DNA scattered throughout these samples. Fingerprints provide police with extremely strong physical evidence tying suspects to evidence or crime scenes. This review briefly recapitulates 30 years of progress in forensic DNA analysis which helps to convict criminals, exonerate the wrongly accused, and identify victims of crime, disasters, and war. The DNA testing of fingerprints can do more than just identify a suspect in a criminal case. DNA fingerprinting works on the basis that each individual’s DNA structure – or genetic make-up – is unique and therefore cannot be forged, faked or altered in any way. DNA fingerprinting with restriction fragment length polymorphisms (RFLP). If the two DNA profiles are a match, then the evidence came from that suspect. It is also used in paternity testing in case of disputes. The DNA collected from a fingerprint can provide enough markers to help techs identify those closely related to the criminal, including their parents and siblings. DNA fingerprinting is the process by which forensic scientists identify a subject by using his DNA. DNA fingerprinting is a method used to identify living things based on samples of their DNA.
