Module 6 Questions and Answers
100% PASS
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. Viruses are neither
eukaryotic or proaryotic
Describe two basic componenents of a virus—ANSWER-1. A virus has genomic material:
meaning it is comprised of either DNA or RNA2. A virus will have a capsid; a membrane-like
protective structure that contains the genetic material
The envelope surrounds the ______________ of some viruses—ANSWER-capsid
true or false: you would expect to see a viral envelop on a virus infecting a plant cell—
ANSWER-false. the overwhelming majority of pant or bacteria-infecting viruses are not
true or false: highly infectious viruses undergo genome replication prior to viral attachment
and entry—ANSWER-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
Uncoating:
, Release:
Replication:
Attachment:
Entry:
New Infection—ANSWER-"1. Attachment: viral receptors bind to host protiens onthe surface
of the cell
2. Entry: the cirus fuses with the host membrane and enters the cell
3. Uncoating: the viral capsid disassembles
4. Replication: the ciral fenome is the blueprint to make copies of itself
5. Release: new virus particles are produces and leave the cell
6. 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 ____- sided polygon capsid—
ANSWER-bacteriophage, 20
True or False: Structurally, bacteriophages are similar to viruses that infect animals—
ANSWER-False. Bacteriophages have a distinct composition and structure
Describe the main differences between lytic and temperate phages—ANSWER-Lytic
bacteriophages replicate within the host bacteria until it ruptures, where as temperate (or
lysoenic) phages primarily exist in a non-replicative state that does not kill the host cell
