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. 1. dsDNA virus 2. ssDNA virus 3. dsRNA virus 4. +ssRNA virus 5. -ssRNA virus 6.

Question
Transcribed Image Text: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.
