Dnaprofiling
DNA profiling uses regions of non-coding DNA that vary between individuals, called short tandem repeats (STRs), to identify a person from their DNA. STR analysis has replaced older DNA fingerprinting techniques. It can analyze small amounts of DNA quickly and is used in forensics, parentage testing, and other applications. Parentage testing involves collecting samples from a child and putative parents, analyzing STR regions through PCR and electrophoresis, and using statistical analysis to calculate probability of paternity.
