What is the first step of the virus reproduction cycle?

• The viruses genetic material (DNA) starts to take over the functions of the cell
• The host cell bursts open, releasing the new viruses
• The virus injects its genetic material into the cell
• A virus attaches to the surface of a host cell

What is the last step in the viral reproduction cycle?

• A virus attaches to the surface of a host cell
• The proteins and genetic material start to assemble in the cell
• The host cell bursts open, releasing the new viruses
• The virus injects its genetic material into the cell
