DNA
DNA analysis is considered one of the most accurate tools for determining guilt or innocence. Post-conviction DNA testing is unique in that it allows the criminal justice system an opportunity to fix mistakes, particularly wrongful conviction.
DNA (deoxyribonucleic acid) molecules contain hereditary (genetic) information. The theory on which DNA testing is based consists of the following: all cells in the human body (except red blood cells) contain DNA; the structure of the DNA of a person is identical throughout a person’s body; the DNA structure is constant from a person’s infancy through their death; and, finally, that no two people (except identical twins) have the same DNA. DNA can be extracted from blood (white blood cells and plasma), skin, tissue, sperm, saliva, vaginal swabs, mouth scrapings, bones, and hair.
