What does DNA show?

Answer 1

DNA (deoxyribonucleic acid) is a collection of your entire genetic code.

You get half of your DNA from your mother, and half from your father.

DNA is comprised of Adenine, Cytosine, Thymine, and Guanine. Some of the codes are responsible for your "genes".

In court, DNA used as criminal evidence CANNOT prove guilt, but it can be used to HELP prove guilt. It CAN be used to prove innocence.

DNA can be taken from spit, blood, semen, hair, fingernails, skin, pretty much anything on your body has DNA. If somebody commits a crime, he or she is likely to leave some form of DNA behind. It is a lot like fingerprints.
