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.
DNA is a nucleic acid consisting of a nitrogenous heterocyclic base, a pentose sugar, and a phosphate group. DNA can be destroyed by the same substances that can destroy other human tissue-intense heat, strong ionizing radiation, a strong base such as sodium hydroxide, or a strong acid such as hydrofluoric acid.
