Viruses

A virus is a (an)

• living thing

• non-living thing

• acellular microorganism

• inorganic structure

The virus head contains...

• the capsid and nucleic acids

• only the protein shell

• the protein shell and capsid

• only the nucleic acids

The tail structure in the virus is important because...

• It's the passageway for nucleic acid to the host cell

• It's used to attach to the host cell

• It's the protein shell that surrounds the genetic material

• It's a Leg-like structure important in head cell recognition

Which of the following structures is the most important to viruses

• spikes

• Nucleic acids

• Tail fibres

• Lipid envelope

Which type of viruses is more resistance to temperature changes?

• Enveloped viruses

• DNA viruses

• Nonenveloped viruses

• RNA viruses

The most common ways to classify viruses are depending on...

• their envelope

• the presence or absence of envelope and type of nucleic acids

• their type of nucleic acids

• the type of DNA contained in the capsid and envelope

The viral cycle that makes the virus multiply inside the host cell is called

• lytic cycle

• Lysogenic Cycle

• Both Lytic and Lysogenic Cycles

• Lysosome Cycle

The viral cycle that makes the virus remains inactive inside the host cell is called

• lytic cycle

• Lysogenic Cycle

• Both Lytic and Lysogenic Cycles

• Lysosome Cycle

What type of virus is the coronavirus?

• Enveloped with RNA

• Nonenveloped with RNA

• Enveloped with DNA

• Nonenveloped with DNA

Lytic and Lysogenic cycle work separately as viral infection mechanisms

• True

• False
