Chapter 6.3, Problem 12CYP
Summary Introduction
To analyse:
The characteristics and nature of viral families in viral classification.
Introduction:
Since viruses are not considered to be living cells, they don’t belong to the classification system that is used for other organisms. The sheer diversity of viruses makes it necessary to make a separate system of classification for them. Structurally, they have been classified as naked or enveloped viruses, helical and icosahedral viruses etc. Many viruses were traditionally named according to their host name or the kind of disease they caused.

- Explain the classifi cation scheme used for viruses.arrow_forwardWhat is meant by a viral titer?arrow_forwardMatch 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.…arrow_forward
