Some viruses can undergo lysis or lysogeny even in the same host. What might be a reason for this? Under what conditions might the virus favor the one strategy over the other?
As a general rule, viruses are not considered to be alive based on several reasons. One such reason is that some viruses use RNA as their genetic material instead of DNA. Which of the five biological themes does this violate? Briefly explain why.
What enzyme is responsible for the production of viral DNA from a retrovirus?

- Viruses are made up of the same biomolecules as cellular organisms (DNA, RNA, proteins, lipids, etc.), which are synthesized through enzymatic dehydration reactions from building blocks and disassembled by enzymatic hydrolysis. They infect cells and replicate themselves using resources from the host cells. Scientists discovered a previously unknown strain of virus in the tropical Pacific Ocean and it can infect higher-order eukaryotes. Initial analysis revealed that the virus is mainly composed of nucleic acids, proteins, and lipids. Chemical analysis after complete hydrolysis revealed the following building blocks (by weight): Chemical components Nucleosides Amino acids Lipids, phosphates, and carbohydrates Percentage by weight 20 30 50 Analysis of percentages of nucleosides yielded the following results (by molar ratio): Nucleosides A G T C U Percentage by mole 19 29 19 29 4 Which of the following events mostly involves hydrolysis reaction after the virus infects…arrow_forwardWhy do the two types of viruses differ if each has plus configuration single stranded RNA as its genome?arrow_forwardExplain the reason why segmentation of the genome provides a strong evolutionary advantage for negative strand viruses.arrow_forward
- Why does a virus need a host cell?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_forwardWhat is a nucleocapsid?
