Concept explainers

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.

List three differences between the structure of HIV and the virus that causes influenza. For one of these differences, explain how the STRUCTURE is key to the FUNCTION of the virus.
Viruses are host-specific, meaning they can only infect specific types of host organisms. For examble, the adenovirus is responsible for the common cold in humans but your dog can't catch a cold from you. Why is this? The proteins on the virus surface can only bind with proteins on the correct host surface. It is an enveloped or non-enveloped virus. The enzymes carried by the virus are compatible with the host. The genome of the virus is made of DNA or RNA.
Describe how lytic bacteriophages are released from their host cells.
Describe the process of reverse transcription of HIV RNA.
Which of the following is a known characteristic or procesds that can lead to genetic changes in some viruses? When two different viral strains of the same type of virus infect a single individual, reassortment/mixing of segmented genome pieces can occur, resulting in new combinations of segments. Genetic rearrangements of the viral genome occurs as a result of duplicate operons in the viral genome undergoing homologous recombination. Environmental conditions trigger the SOS response in viruses, and leads to generation of errors/mutations in the viral genome. Viral RNA polymerases display proofreading capability in replicating the viral genome of certain viruses.
A cell infected with lambda bacteriophage can follow one of two pathways: the lytic or lysogenic pathway. Describe the similarities and differences between the structure of cI and Cro, paying particular attention to the features that allow them to carry out their different functions.
Moderna 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.
Some 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.
Describe the classes of viruses based on theirgenomic characteristics. For each class, describe how viralmRNA is made and how the viral genome is replicated.
Retroviruses, like the HIV, contain an enzyme called reverse transcriptase. Explain the flow of genetic information in HIV.
Consider the phase variation of flagella in Salmonella. Describe the phenotype of a cell in which hin is deleted. Will it be motile? Will it undergo phase variation? Which flagellin(s) will be used, if any? Name two bacterial defenses against bacteriophages and explain how they work How might a phage evolve resistance to the CRISPR host defense?
The size of a DNA fragment that can be inserted into an unmodified λ vector is very limited. Large segment in the central region of the λ DNA molecule can be removed without affecting the ability of the phage to infect Escherichia coli cells. However, the deletion of this non- essential region does affect the life cycle of the bacteriophage. Explain this statement.
