Which of the following is NOT true about Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and the disease it causes? Which option is the answer: 1. During Coronavirus Disease (COVID-19), a person is the most highly infectious for others during the period of peak viral load and symptoms 2. As it is transmitted through the global human population, the virus is highly genetically stable and does not change 3. Some people who become infected with SARS-CoV-2 will not develop signs and/or symptoms of disease 4. The severity of disease varies greatly, depending on age and/or underlying predisposing conditions 5. Emerging SARS-CoV-2 variants may sometimes be more transmissible than previous strains

Compare and contrast the role and types of viral mutations in 1918 influenza type A virus and SARS-COV-2 in the respective pandemics, paying particular attention to: 1. causes of mutations 2. Key mutations responsible for generating highly pathogenic viral strain. 3. effects of mutated viral gene products on host immune system. 4. effects of newly emergent viral strain on virus spread worldwide.
Which of the following is NOT true about the current coronavirus global pandemic (COVID-19)? Laboratory diagnosis of infection is based on polymerase chain reaction (PCR) testing of patient samples for RNA from the causative virus Nucleic acid vaccines to prevent COVID-19 (and/or its most severe forms) are authorized for use in the US Caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Person-to-person transmission can occur through respiratory secretions (droplets and/or aerosols) None of the other four answers (All are true about COVID-19
Indicate whether the following sentences is either True or False and CORRECT the wrong sentences ( please answer the two questions 1 and 2) : 1. Simian Virus 40 (SV40) is an example of is a circular ssDNA belong to Polyomavirus, was first isolated from primary cell cultures derived from rhesus monkey kidneys, and activates p53. 2. SARS-COV-2 is an enveloped, icosahedral virus that is surrounded by a lipid bilayer and causes COVID-19 pandemic .
Discuss the role of each of these factors in the causation of the COVID-19 pandemic. Be specific with respect to the molecular mechanisms responsible for these effects: 1. zoonotic virus origins 2. immunologically naive population 3. SARS-CoV-2 virulence factors affecting transmissibility 4. evolution of immune-resistant virus variants.
Choose all the true statements regarding coronavirus proteins. Vaccine preventable diseases include COVID-19. For coronaviruses, it is more likely to find evolving mutations in the portion of the spike protein than the nucleocapsid protein. Mutations in the genetic code for the spike protein will produce 3D changes that are more likely to affect vaccine efficacy than changes to the nucleocapsid protein code. The nucleocapsid protein interacts with viral nucleic acid specifically whereas the spike protein interacts with the host protein non-specifically.
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.
Answer the two questions below by reading the article 1, What was discovered in this article and how is it interesting 2, How is this discovery in the article related to genetics Article The novel SARS-CoV-2 coronavirus that emerged in the city of Wuhan, China, last year and has since caused a large scale COVID-19 epidemic and spread to more than 70 other countries is the product of natural evolution, according to findings published today in the journal Nature Medicine. The analysis of public genome sequence data from SARS-CoV-2 and related viruses found no evidence that the virus was made in a laboratory or otherwise engineered. "By comparing the available genome sequence data for known coronavirus strains, we can firmly determine that SARS-CoV-2 originated through natural processes," said Kristian Andersen, PhD, an associate professor of immunology and microbiology at Scripps Research and corresponding author on the paper. In addition to Andersen, authors on the paper, "The proximal…
true or false? The genomic analysis found that SARS-CoV-2 belongs to the Betacoronavirus group, lineage B For people with COVID-19 disease, the infectious period begins 2 days before the start of signs and symptoms of disease and the end of the infectious period is defined as when it is at least 10 days after the onset of illness
