BIOD 171 MODULE 6 QUESTIONS AND
ANSWERS
1. True or False. Because the genome is contained within an
enclosed space (much like the nucleus of a cell), viruses are
classified as eukaryotic.: False
2. True or False. Although viruses may contain their genome within
an enclosed space (much like the nucleus of a cell), it is considered
neither eukaryotic nor prokaryotic.: True
3. Describe the two basic components of a virus.: A virus has genomic
material made up of either DNA or RNA and a capsid which is a protective structure that
contains genetic material
4. True or False. You would expect to see a viral envelope on a virus
infecting a bacterial cell.: False
The overwhelming majority of animal viruses are enveloped whereas the majority of plant or bacteria-
infecting viruses are not.
5. The envelope surrounds the of
some viruses.: Capsid
