Place the following viral life cycle steps in order beginning with viral
attachment and provide a description of each step.
(AEURRN) - answer 1. Attachment: viral receptors bind to the new cell
surface
2. Entry: virus combines with host membrane and enters the cell
3. Uncoating: viral capsid disassembles
4. Replication: viral genome makes copies of itself
5. Release: new virus particles are produced and leave the cell
6. New Infection
Attachment - answer viral receptors bind to the new cell surface
Uncoating - answer viral capsid dissassembles
Release - answer new virus particles are produced and leave the cell
Replication - answer viral genome makes copies of itself
Entry - answer virus combines with host membrane and enters the cell
New infection - answer newly produced viruses that left host cell go and
infect new cells
