Microorganisms: Viruses: Shmoopvirus is Infectious True or False
Which of the following is NOT involved in any type of virus membrane fusion?Cell receptor
If you treat a cell with a membrane-impermeable protease and then add a virus to it, the cell will not be infected. Why not?The protease removes the virus receptor from the cell.
What does the previous answer tell you about the virus?The virus requires a cellular receptor to enter the cell.
How can you prove that a virus does NOT require low pH to enter a cell?Mix infected cells with uninfected cells
