DNA is the chemical in the cells of plants and animals which
carries inherited characteristics, or genetic information. DNA testing
(l) can be used to identify each person as a unique individual on the basis of that
genetic information. It (2) is also called 'genetic fingerprinting'. The results of DNA
testing are now being accepted as evidence in cases where it (3) is believed that
the wrong person (4) may have been convicted of a crime. In recent years, more than seventy
people (5) have been shown to be innocent through DNA testing. Many of those people (6)
had been sentenced to life in prison. In one case, a man (7) was released after nineteen years in
prison. DNA testing (8)has also been used in some murder cases that (9) would never have been solvedwithout it.
