BIOD 171: INITIAL EXAM TEST
1. The surrounds the capsid of some viruses.
Envelope.
2. True or False. You would expect to see a viral envelope on a virus infecting
a plant cell.
False. The overwhelming majority of animal viruses are enveloped whereas the
majority of plant or bacteria-infecting viruses are not.
3. Rank the following viruses based on their size from
largest to smallest: Orthomyxovirus
Polioviru
s
Variolavi
rus
Variolavirus (~200nm) > Orthomyxovirus (100-150nm) > Poliovirus (~30nm)
1. What linear, double-stranded, enveloped DNA virus is the first virus (as
of Oct. 26, 1977) to be officially declared eradicated?
Smallpox (Variola virus). Although once a major cause of death in the world, a
smallpox vaccine was developed in 1796 by Edward Jenner. Global vaccination
efforts have prevented smallpox from appearing in humans since October 26,
1977, making smallpox the first infectious disease ever to be eradicated.
2. What small (~30nm) single-stranded, non-enveloped RNA virus targets
the CNS (central nervous system), causing potentially catastrophic damage
to motor neurons?
, BIOD 171: INITIAL EXAM TEST
Polio, also known as poliomyelitis.
3. By whom and where was the first Polio vaccine developed?
Jonas Salk and his research team developed the polio vaccine at the University of
Pittsburgh in 1955.
4. Which subtype of Influenza is the most virulent?
Influenza A.
1. True or False: A virus is considered a microorganism.
False. Viruses are not living and as such are not considered microorganisms.
Viruses can, however, be classified as microbes, a more general term that
includes microorganisms and viruses.
2. What is the smallest biological unit of life?
A cell.
3. At a generalized level, all cells are comprised of what?
Macromolecules*
*A student may also answer: Proteins, Lipids, Nucleic acids and
Polysaccharides but they must answer with all four to be fully correct.
1. Animalia, Plantae, Fungi and Protista are all classification under what type
of organism?
A. Bacteria
B. Eukarya
