b.) How do you think this feature affects the stability of the viral genome? (hint use figure below)
Mutation rates in different types of viruses. Estimates obtained for viruses belonging to the major indicated groups are shown as a function of genome size. This reveals an effect of genetic material (RNA/DNA) and genome size on viral mutation rates.
The RNA genomes of some RNA viruses resemble the messenger RNA (mRNA) of their eukaryotic hosts. What advantage would an RNA virus gain by having this type of genome?

- Describe the mechanism of replication of the eukaryotic virus SV40.arrow_forwardThe genome of a retrovirus can integrate into the host cell genome. What gene is unique to retroviruses, and why is the protein encoded by this gene absolutely necessary for maintaining the retroviral life cycle?arrow_forwardSome retroviruses that have a wide host range have been developed for use in treatment of diseases or syndromes. These viruses do not result in a productive infection because they lack critical genes for viral replication, but they do carry DNA sequences that allow them to be packaged into infectious particles. Once in the host cell the viral DNA is released and integrates into the cell's genome. The advantage to this strategy is that the delivery of the DNA is very efficient. What is one possible problem of using a virus that can integrate into the human nuclear genome? Multiple Choice The virus carries genes that will interfere with host cell activities. The viral DNA sequences could still cause a disease. Since the viral DNA sequences no longer contain essential genes for viral replication the host cell may not be able to replicate either. The integration could disrupt an essential gene or genes.arrow_forward
- The complete coronavirus genome sequence from the first known patient infected with SARS-CoV-2 was published on January 10th 2020, just a short time after the patient had been hospitalized in China with respiratory symptoms. They did this so quickly using nanopore sequencing. Scientists compared the genome sequence from the new coronavirus (SARS-CoV-2) with the genome sequences from several other coronaviruses and they did identify a sequence unique to the SARS-CoV-2 strain. This unique sequence was in the N gene of the viral genome. What protein is made from the N gene of the virus?arrow_forwarda variant of the SARS-CoV-2 virus has been found in brazil. this variant contains the mutation K417N, where the amino acid K has been mutated to the amino acid N. K and N refers to the one letter codes of the amino acids. a) state the names of the amino acids K and N. b) state one difference between the properties of these 2 aminoacidsarrow_forwardA particular animal virus requires the use of DNA polymerase from its host, since it does not possess its own DNA polymerase enzyme. Which of the following assumptions in A-D would likely be correct regarding this virus? A) O This virus could not be a retrovirus type. B) OIt could be a (-) ss RNA virus. C) O It could be a (+) ss RNA virus. D) O The vVirus life cycle very likely includes going to the host cell nucleus. E) O All ofA-D are correct assumptions.arrow_forward
- 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.…arrow_forwardModerna and Pfizer vaccines for COVID-19 use mRNA to the Spike protein combined with lipids. Which of the following is/are advantages of this type of vaccine compared to an inactivated virus vaccine? Select ALL correct answers. a) The vaccine is more stable for transport. b) The vaccine does not contain the virus so it cannot give you COVID-19. c) The vaccine can be rapidly produced in a slightly different form to protect from variants of SARS-CoV-2. d) The vaccine does not need a booster.arrow_forwardWhat is the function of reverse transcriptase in retroviruses? a) It converts viral RNA into double-stranded DNA Ob) It uses viral RNA as a template for making complementary RNA strands Oc) It translates viral RNA into proteins d) It uses viral DNA as a template for RNA synthesisarrow_forward
