Description

DNA is made up of four base chemicals, adenine, guanine, cytosine and thymine. These pair with each another to form a double-helix structure. DNA is passed down from parent to child through chromosomes. Each human cell has 46 chromosomes, half inherited from the mother and half from the father. Chromosomes and the DNA they contain make it possible to determine someone's genetic lineage.

DNA testing evolved from the study of genetics, which began in the late 1800s when Gregor Mendel first studied the phenomenon of inherited traits in pea plants. His work laid the foundation for the discovery of DNA, or deoxyribonucleic acid, the molecules that contain our genetic makeup. Despite the fact that nearly 99 percent of human DNA is similar, there is enough of a difference in the remaining 1 percent to make it possible to identify an individual.
