Scientists are developing a medication to stop a virus from infecting target cells. On which step of the replication cycle should they focus?

Question

A.Step 1, when the virus binds to a receptor on the cell membrane
B.Step 2, when the virus uses its genetic material to make copies of its genome
C.Step 3, when the viral genetic material and proteins form new viral particles
D.Step 4, when new viral particles spread out of the host cell

Answer 1

To stop a virus from infecting target cells, scientists should focus on A. Step 1, when the virus binds to a receptor on the cell membrane. This is the initial step in the viral replication cycle where the virus attaches itself to the host cell, and inhibiting this interaction would prevent the virus from entering the cell and thus stop the infection process. Blocking this early step can effectively prevent the virus from establishing an infection in the target cells.
