Place the steps involved when a person gets infected with SARS-CoV2.

Question

Put the steps involved when a person gets infected with SARS-CoV2 in order:

a) The virus enters a person's mouth/ nose

b) The virus inserts its RNA into a cell

c) The virus RNA hijacks the cell and the cell beings to make hundreds of copies of the virus

d) The S protein on the outside of the virus attaches to the ACE2 receptor of a person's lung and 10 minutes have passed

e) Infected body cells send out an alarm of viral invasion

f) the lung cell dies and 10 hours has passed

Answer 1

Hi Alison,

The order of steps should be:

a) The virus enters a person's mouth/ nose

d) The S protein on the outside of the virus attaches to the ACE2 receptor of a person's lung and 10 minutes have passed

b) The virus inserts its RNA into a cell

c) The virus RNA hijacks the cell and the cell beings to make hundreds of copies of the virus

e) Infected body cells send out an alarm of viral invasion

f) the lung cell dies and 10 hours has passed

The way that the virus starts hijacking the cell is by first attaching to its ACE2 receptor. That's how it gets its RNA into the cell.
