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

Other viruslike particles called prions are composed primarily of a protein tightly integrated with a small nucleic acid molecule. Viruses are generally classified by the organisms they infect, animals, plants, or bacteria.ucleic Acid-Just as in cells, the nucleic acid of each virus encodes the genetic information for the synthesis of all proteins. While the double-stranded DNA is responsible for this in prokaryotic and eukaryotic cells, only a few groups of viruses use DNA.
