- Can you please pick the right answer in each parentheses? The spike protein of SARS-CoV-2 is a carbohydrate-modified protein that ["bind the RNA genome of the virus", "", "is on the surface of the viral particle", ""] and plays a role in both ["replication of the viral genome", "recognition of host cell"] and ["packaging of viral genome for export", "fusion of viral envelope with host cell plasma membrane"] . Importantly, earlier work on spike proteins from other corona viruses showed that this molecule ["remarkable resistance to immune response", "shows remarkable conformational changes"] and only one of these served as a good antigen for vaccine development. A critical discovery in advancing the development of our current vaccines was determining what changes in the amino acid sequence would ["block degradation of the spike protein", "stabilize the conformation of the protein found on the viral particle"]. This…Topic is SARS-CoV-2 Describe at least 2 different, scientifically-tested strategies that scientists or doctors use to either treat or prevent the spread or progression of the pathogen or the resulting disease. These strategies can include drug treatments, behavioral changes, and/or genetic interventions (ex- CRISPR or genetic modifications). For each strategy you list, you must (1) cite at least one scientific study that tested this strategy and its outcomes (how well does this strategy work). (2) explain how the strategy helps at the cellular or physiological level. (ex- If you list a drug, explain how the drug works in the body to prevent/repair/replace the function of the damaged tissue or organ).please help summary Results Labeling HIV-1 Capsids with a GFP Fluid Phase Marker. To determine whether viral cores in infected cells retained their integrity, we utilized a previously described HIV-1 vector in which GFP was inserted between matrix (MA) and CA (pNL4-3 Gag-iGFP) (35) (Fig. 1A). Proteolytic processing during virion maturation releases GFP from the Gag precursor, some of which remains trapped inside the capsid and is released upon loss of core integrity (Fig. 1B). We also utilized a previously described RNA stem-loop system in which 18 copies of BglG stem loops (BglSLs) were engineered into the HIV-1 genome in place of vif/vpr to facilitate the detection of nascent HIV-1 genomic RNA at the HIV-1 transcription site (Fig. 1A). This system can be used to identify the capsids that lead to productive infection and determine the nuclear location of integration (25). Virions were produced by cotransfection of an HIV-1 vector expressing Gag-iGFP and a vector expressing wild-type…

- Ch. 15-1 In 1918, an influenza pandemic that originated with avian flu killed 50 million people. Researchers isolated samples of that virus from bodies of infected people preserved in Alaskan permafrost since 1918. From the samples, they sequenced the viral genome, then reconstructed the virus. The reconstructed virus is 39,000 times more infectious than modern influenza strains, and 100 percent lethal in mice. Understanding how this virus works can help us defend ourselves against other strains that may arise. For example, discovering what makes it so infectious and deadly would help us design more effective vaccines. Critics of the research are concerned: If the virus escapes the containment facilities (even though it has not done so yet), it might cause another pandemic. Worse, the published DNA sequence and methods to make the virus could be used for criminal purposes. Do you think this research makes us more or less safe?topic: Zika Virus write summary on a virus and its tropism for specific hosts, tissues, or cells. For example, you may want to discuss: the distribution/expression of the relevant cell surface receptor or other factors modulating viral entry, or you may want to focus on the environment in a specific niche that makes it conducive for infection by the virus. You can also choose to research a tangential topic like how tropism is considered in vaccine development. thank you-you want to design a vaccine that contains DNA that can fight against new variant (MU) of COVID-19 strain. You know that you can alter the information in DNA and can make a viral-vector based vaccine. What kind of virus you will use and why? not a writing assignment just few sentences
