Question
Chapter 4, Problem 21P
Interpretation Introduction
Interpretation:
The definition of retrovirus along with its flow of information as compared to an infected cell should be explained.
Concept introduction:
The flow of genetic information depends on the genetic code that is DNA or RNA.
Retrovirus is a type of virus which has RNA as a genetic medium. It uses reverse transcriptase to convert RNA into DNA which is integrated into a host cell.

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…

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…
