Viruses and Kingdoms Practice Quiz

What do viruses need to reproduce?

• they need genetic material
• They need a host cell
• They need  bacteria
• They need insulin

Viruses 

• have many cells
• are misfolded proteins
• are a protein coat around genetic material
• endospores

What is the main function of the projections on the surface of a virus?

• They aid in respiration
• They help the virus grow
• They help the virus invade its host by attaching to specific sites on the host
• They help the virus digest food molecules

Reasons that viruses are considered to be nonliving is because

• They cannot make proteins
• all of the above

Which can be treated with antibiotics?

• Virus
• Bacteria
• Mutagen
• Parasite

What do viruses have in common with living cells? They both...

• store genetic information
• have chloroplasts
• use glucose for cellular respiration
• have endoplasmic reticulum

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
