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 particles contain the viral genome packaged in a protein coat called the capsid. For some viruses, the capsid is surrounded by lipid bilayer that contains viral proteins, usually including the proteins that enable the virus to bind to the host cells. This lipid and protein structure is called the virus envelope, and is derived from the host cell membranes. The capsid and envelope play many roles in viral infection, including virus attachment to cells, entry into cells, release of the capsid contents into the cells, and packaging of newly formed viral particles.
