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

• tail

• nucleus

• capsid

• glycoprotein

Which viral life cycle kills its host cell by bursting out?

• lytic

• mitosis

• lysogenic

• S phase

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

• lytic
• mitosis
• lysogenic
• S phase

Is a virus considered living or non-living?

• Living
• Non-Living
• Neither

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
