DNA fingerprinting
(genetic fingerprinting) A scientific technique in which an individual’s genetic material (DNA) is extracted from cells in a sample of tissue and analysed to produce a graphic chart that is unique to that person. The technique may be used as evidence of identity in a criminal or civil case and has been notably successful in both paternity and rape cases. DNA samples (e.g. of hair) may be taken from suspects in accordance with the Police and Criminal Evidence Act 1984 and after conviction for any offence punishable by imprisonment. |
