Answered by The Community. Making the world better, one answer at a time. The physical properties of DNA (deoxyribonucleic acid) is first structured like a twisted ladder made up of 4 different base chemical's adenine, guanine, cytosine, and thymine. To the naked eye though DNA has color in between clear and white, and is stretchy to an extent, if stretched to far it will snap.
That is, the DNA in an individualâs white blood cell contain the same characteristics as DNA in the skin, semen, saliva, hair, and every other part of the anatomy. Since each personâs DNA is unique (except identical twins), DNA is arguably the single most important tool of investigation.hat is, the DNA in an individualâs white blood cell contain the same characteristics as DNA in the skin, semen, saliva, hair, and every other part of the anatomy.
