Section 6.3 Viruses: Structure, Function, and Uses. A virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a virus can direct the cell machinery to produce more viruses. Most viruses have either RNA or DNA as their genetic material.he T phages of E. coli are large lytic phages that contain a single molecule of double-stranded DNA. This molecule is about 2âÃâ10 5 base pairs long in T2, T4, and T6 viruses and about 4âÃâ10 4 base pairs long in T1, T3, T5, and T7 viruses.
Virus Structure. Viruses are not plants, animals, or bacteria, but they are the quintessential parasites of the living kingdoms. Although they may seem like living organisms because of their prodigious reproductive abilities, viruses are not living organisms in the strict sense of the word.ome scientists speculate that viruses started as rogue segments of genetic code that adapted to a parasitic existence. All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules.
