Virus Review

During the lytic infection by a virus, the host cell is-

• destroyed
• copied
• passed on to the lysogenic cycle
• not affected

Which statement regarding viruses is true?

• a virus can only reproduce inside of a living cell
• viruses do not contain DNA
• viruses are unicellular
• viruses are generally larger than cells

The capsid of a virus protects the virus from the external environment. What structure is this similar to in a plant cell?

• ribosome
• cell membrane
• vacuole
• cell wall
