True or False. Because the genome is contained within an enclosed space (much like the
nucleus of a cell), viruses are classified as eukaryotic. - ANSWER False
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. -
ANSWER True
Describe the two basic components of a virus. - ANSWER A virus has genomic
material made up of either DNA or RNA and a capsid which is a protective structure that
contains genetic material
True or False. You would expect to see a viral envelope on a virus infecting a bacterial cell. -
ANSWER False
The overwhelming majority of animal viruses are enveloped whereas the majority of plant
or bacteria-infecting viruses are not.
The envelope surrounds the _________ of some viruses. - ANSWER Capsid
The ________ surrounds the capsid of some viruses. - ANSWER envelope

Rank the following viruses based on their size from largest to smallest:
Orthomyxovirus
Poliovirus
Variolavirus - ANSWER Variolavirus

True or False: Highly infectious viruses undergo genome replication prior to viral attachment
and entry. - ANSWER False
Place the following viral life cycle steps in order beginning with viral attachment and
provide a description of each step.
Uncoating:
Release:
Replication:
Attachment:
Entry:
New infection: - ANSWER 3- Uncoating: the viral capsid disassembles
5-Release: New virus particles are produced and leave the cell
4-Replication: the viral genome is the 'blueprint' to make copies of itself
1-Attachment: viral receptors bind to host proteins on the surface of the cell
2-Entry: the virus fuses with the host membrane and enters the cell
6-New infection: newly produced viruses that left the host cell now go on to infect new cells.
