Explain why viral shapes are significant when it comes to host identification and infection

Understand the progression and scope of viral infection.

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.…
