Most viruses are too small (100â2,000 Angstrom units) to be seen with the light microscope and thus must be studied by electron microscopes.

DNA is composed of nucleotides bounded together by a backbone and connected at the center by hydrogen bonds. A nucleotide is made up of three parts: a phosphate group, a 5 carbon sugar (deoxyribose in DNA), and a nitrogenous base (adenin, thymine, guanine or cytosine).DNA is a nonparallel molecule, so the composition of the backbone is a combination of the phosphate and sugar molecule that composes the nucleotide.NA is composed of nucleotides bounded together by a backbone and connected at the center by hydrogen bonds.
