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.
Answer the following and inlcude the references SARS-CoV-2, the virus that causes CoVid-19, belongs to the Coronaviridae family. Viruses under this family have a genome made of single-stranded positive-sense RNA. Is this similar to the viral genome of HIV? If so, do you think that – in theory – they would have similar replication cycles? Do you think that ART combinations/options might help in suppressing the viral replication of SARS-CoV-2? Expound.
Which of the following is the most likely explanation for an individual who lacks CCR5 as a result of a homozygous defect in the CCR5 gene becoming infected with HIV? a. The mutated CCR5 genes reverted to the normal form, rendering macrophages susceptible to macrophagetropic HIV variants. b. The macrophage-tropic HIV variant entered host cells using CD4 alone. c. The viral nucleic acid alone was taken up by cells, as in cell transformation by bacterial DNA. d. The individual had received a transplant of HIV-infected cells expressing normal CCR5. e. The primary infection involved a lymphocyte-tropic strain of HIV that used CXCR4 as its co-receptor.

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?
Which nucleic-acid based technique will detect norovirus? A. Fluorescent In Situ Hybridization (FISH) probes B. PCR with primers specific for the genome of this virus C. Terminal Restriction Fragment Length Polymorphism (T-RFLP) D. reverse transcription PCR with specific primers A patient's blood sample tests positive for the antigen to Vibrio cholerae. Which of the following interpretations is correct? A. This person has cholera. B. This person was exposed to any species of Vibrio. C. This person was exposed to V. cholerae recently. D. This person had cholera at some point in their lifetime.
A common way to prevent infectious viral diseases, such as COVID-19 and the flu, is to develop a vaccine for the virus that causes them. Vaccines can be made from a virus’s proteins or other parts, or from a virus that has been inactivated and is no longer harmful. Some vaccines, such as the flu vaccine, need to be modified every year to keep up with changes in the virus. Studies have shown that SARS-CoV-2 has a slower mutation rate than the influenza virus, which causes the flu. This means that mutations occur less frequently in SARS-CoV-2’s genome than in the influenza virus’s genome. Based on the information above, explain why it may be possible to develop a SARS-CoV-2 vaccine that would not have to be modified as often as the flu vaccine.
Why can’t retrotransposons move from one cell to another like retroviruses?a. Because they do not encode the Env proteinb. Because they are nonautonomous elementsc. Because they require reverse transcriptased. a and b are both true.
Transmission studies suggest that there are at least three (3) different variants of the SARS-CoV-2 virus circulating in Latin America and the Caribbean. Discuss a recombinant DNA technology strategy that could be used to verify this claim.
Two theoretical genetic strains of a virus (a-b-c- and a+b+c+) were used to simultaneously infect a culture of host bacteria. Of 10,000 plaques scored, the following genotypes were observed. Determine the genetic map of these three genes on the viral chromosome. Decide whether interference was positive or negative. a+ b+ c+ 4100 a- b+ c- 160 a- b- c- 3990 a+ b- c+ 140 a+ b- c- 740 a- b- c+ 90 a- b+ c+ 670 a+ b+ c- 110
Please consider the figure attached i. The ordinate (i.e., 'y-axis') represents values for the C or G nucleotide base proportion in sequences (or, in this case, genomes).ii. Influenza viruses that infected birds or moved from birds to humans without spreading are characterised by higher A + U content relative to influenza viruses that infected humans for long time periods.iii. Influenza viruses adapted to human hosts are characterised by lower G + C content relative to influenza viruses that infected birds or moved from birds to humans without spreading. iv. Human and swine influenza A H1N1 strains evolved from a birdlike G + C state to a humanlike G + C state since 1918. v. Data such as those depicted in the figure have been interpreted as evidence that the 1918 influenza virus strain originated from a bird influenza virus population. Question 1 options: A) Statement ii conveys accurate information. B) Statements ii,…
Some older vaccines used a weakened strain of the pathogenic virus in the injection in the hope that the weakened virus would induce an immune response without causing disease. The virus vectors used in genetic engineering have all the harmful virus genes cut out and replaced with the foreign gene, such as one that makes a protein that is absent in the human patient. Which type of viral vaccine would you prefer to take as the safest option? Why? Some Covid 19 vaccines in development use the adenovirus, a common vector used in gene therapies, to inject the mRNa for the spike protein into human muscle cells. Why might vaccines using a virus vector be more likely to need only refrigeration and not deep-cold storage, given what you know about viruses?
