What part of a virus is the protein capsule that houses the genetic material (DNA/RNA)?

• tail
• nucleus
• capsid
• glycoprotein

Which viral life cycle allows viral genetic material to lay dormant while the host cell reproduces?

• lytic
• mitosis
• lysogenic
• S phase

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
