Question:-
the unique biology of retroviruses(AIDS) discuss why we have no vaccine and no cures at this time.
Step by step
Solved in 4 steps
- Please help me with this question. More than one answer may be correct. The graph relating to the information is included below. The above graph is looking at the relative entry of SARS-CoV2 isolated spike proteins into human cells in culture at two times points: before introduction of the virus to the cell culture (0 minute) and 5 minutes after introduction of the virus to the cell culture. CHC stands for "clathrin heavy chain" and siRNA stands for small interfering RNA, which is often used in experiments as an easy method to stop expression of a certain gene. So in this case, the CHC siRNA would stop cellular production of CHC. The control siRNA introduces a small RNA fragment that does not match any gene as a negative control. Imagine that the experiment was then allowed to run for 500 minutes in addition to five minutes? How would the relative uptake of the spike protein into the control siRNA cells compare after 500 min to the 5 minute treatment? Options: 500 min time point would…Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below. The above graph is looking at the relative entry of SARS-CoV2 isolated spike proteins into human cells in culture at two times points: before introduction of the virus to the cell culture (0 minute) and 5 minutes after introduction of the virus to the cell culture. CHC stands for "clathrin heavy chain" and siRNA stands for small interfering RNA, which is often used in experiments as an easy method to stop expression of a certain gene. So in this case, the CHC siRNA would stop cellular production of CHC. The control siRNA introduces a small RNA fragment that does not match any gene as a negative control. From the above figure, you can conclude what about the process that allows the SARS CoV-2 virus entry into the cell? Options: The spike protein is not involved in cell entry, contrary to popular belief This is evidence for clathrin-mediated endocytosis as the…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.
- 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-Multiple Matching.
