DNA forensics: The application of DNA technology and the knowledge of DNA genetics to the practice of forensic medicine and to the power of legal medicine. Crime scene investigation has been markedly changed -- some would say revolutionized -- by the advent of DNA forensics. This has led to the invention of devices for DNA forensics. One is a plate of glass about the size of a hand is etched with very thin channels and reservoirs. A minute sample of DNA is moved between reservoir and channel through timed electric pulses. These thin channels then act like capillary tubes and can resolve the constituents of this minute sample of DNA.
DNA, or deoxyribonucleic acid, is the fundamental building block for an individual's entire genetic makeup. It is a component of virtually every cell in the human body. Further, a person's DNA is the same in every cell. For example, the DNA in a man's blood is the same as the DNA in his skin cells, semen, and saliva.DNA is a powerful tool because each person's DNA is different from every other individual's, except for identical twins.Because of that difference, DNA collected from a crime scene can either link a suspect to the evidence or eliminate a suspect, similar to the use of fingerprints.NA is a powerful tool because each person's DNA is different from every other individual's, except for identical twins.
