DNA of individuals is, like the fingerprint, unique and offers an appropriate tool for identification. The modern genetic fingerprinting is performed here using PCR to show differences in the non-coding repetitive DNA sequences of individuals, allowing their identification. Several application domains of DNA profiling, such as criminal analysis, relationship testing or examination of ancient DNA are elucidated here based on real examples.
