Viral DNA synthesis cannot take place in a resting cell. How is this problem solved? Which one is correct?   Early viral proteins like T antigen and E1A inactivate Rb protein   Viral late promoters are activated by DNA replication   DNA polymerase is encoded in the viral genome   Viral DNA genomes have multiple origins of replication

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.…

Viruses encode many ways to antagonize the Pkr pathway. Which is not a direct target of viral Pkr antagonists? Group of answer choices stress granules eIF2-alpha Pkr dsRNA

Which best describe the HIV REV protein? Code for proteins necessary for synthesis of the viral capsids. Code for proteins that is cleaved to produce reserve transcriptase. Binds a specific stem-loop structure in the viral RNAs into cytosol. None of the above.

Would you be able to help with this? Number 1. I’ve watched the video and can’t figure it out :/

Which of the following components of a virus is NOT encoded by its own genome? O capsid of HIV O lipid bilayer of HIV envelope O spike glycoproteins of HIV envelope O anchoring structures of bacteriophage

Some viruses such as HPV are linked to mutations causing certain types of cancer. What part of a virus life cycle can add mutations to host DNA?       What type of bacteriophage, as defined by life cycle, could do this?

Please briefly state the importance of each stage of viral replication. Do not just restate what each stage does. In addition, why must a virus infect a cell to survive and reproduce?

After replication at the site of entry, some viruses remain localized, while others disseminate. Which of the following does not determine the outcome? Group of answer choices Presence of a lipid membrane on the virion Whether the virus can cross the basement membrane Directional release of virus from polarized cells Establishment of viremia Transport of virions in immune cells

O O O A new virus is discovered. Its RNA genome encodes several proteins, including a reverse transcriptase enzyme. What can you conclude about replication of this virus? Its replication involves a double-stranded RNA intermediate Its replication involves a DNA copy of its genome Its replication depends entirely on cellular enzymes Its replication is entirely independent of cellular enzymes 00 A deficiency in Base Excision Repair (BER) would primarily sensitize you to mutations caused by radiation, X-rays O Chemicals in smoke, and UV radiation O Unavoidable, spontaneously occurring DNA damage
