what are physical properties of dna
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.
