DNA (Deoxyribonucleic acid) is the genetic material present inside the nucleus of all eukaryotic cells.
Samples as small as few skin cells also contain DNA and the presence of DNA in skin cells is often used to identify the DNA of a person in a crime scene.
Further, with the use of PCR technology, the small amount of DNA obtained from skin cells can be amplified into many copies.
