GUARANTEED
Rank the following viruses based on their size from largest to smallest:
orthomyxovirus, poliovirus, variolavirus
Variolavirus>Orthomyxovirus>Poliovirus
Rank the following viruses based on their size from largest to
smallest:Paramyxovirus, Poliovirus, Smallpox virus
Smallpox>Paramyxovirus>Poliovirus
True or False: Viral replication occurs after it attaches and enters the host cell
True. The viral genome is never replicated before attachment and entry
True or False: Highly infectious viruses undergo genome replication prior to viral
attachment and entry.
False. The viral genome is never replicated before attachment and entry regardless
of its level of infectivity.
Place the following viral life cycle steps in order beginning with viral attachment
and provide a description of each step (short answer)
Uncoating: the viral capsid disassembles
Release: New virus particles are produced and leave the cell
Replication: the viral genome is the 'blueprint' to make copies of itself
Attachment: viral receptors bind to host proteins on the surface of the cell
Entry: the virus fuses with the host membrane and enters the cell
, 2
New Infection: newly produced viruses that left the host cell now go on to infect
new cells
A virus that infects bacteria is called a _____ and contains a _____ -side polygon
capsid (fill in the blank)
Bacteriophage; 20-sided
True or False: Structurally bacteriophages are similar to viruses that infect animals
False. Bacteriophages have a distinct composition and structure
True or False. Structurally, bacteriophages are distinct from viruses that infect
plant or animal cells.
True. Bacteriophages are structurally distinct from viruses that infect plant and
animals cells.
Identify the following components of a bacteriophage (picture)
1. Capsid
2. Collar
3. Tail
4. Base
5. Tail fibers
Describe the main differences between lytic and temperate phages (short answer)
Lytic bacteriophages replicate within the host bacteria until it ruptures, whereas
temperate phages primarily exist in a non-replicative state that does not kill the
host cell
Lytic phages replicate all viral proteins needed for the assembly of new virus
particles whereas lysogenic phage genomes are integrated into the host genome
but production of viral proteins is suppressed
