Question
Match each of the following replication classes of viruses with the one description that best
describes it.
This virus class is composed of
segmented and non-segmented
helical viruses that carry an
RdRp within the virion into the
cell. Example: Rabies virus
These viruses are non-
enveloped, icosahedral, have
segmented genomes, and carry
their own RNA-dependent RNA
polymerase. The viral genome
is copied following assembly.
Example: Reovirus
This is the only class of RNA
viruses whose genome is
replicated by cellular enzymes
and not an RNA-dependent
RNA polymerase.
Cellular DNA polymerases
replicate this virus's non-
integrated genome, although
transcription is not the initial
event that takes place in the
process. Example:
Parvoviruses
In this class of viruses,
transcription occurs before
genome replication because
viral proteins are involved in
replicating the genome.
Example: Adenovirus
This class of viruses forms
circular DNA and creates pre-
genomic RNA using host RNA
polymerases.
This ubiquitous class of viruses
has infectious nucleic acid and
uses negative-sense
antigenomic RNA as a template
to replicate its genome.
