Viruses

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

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

When a virus invades a living cell, its _______
takes over the cell's functions.

• outer coat
• genetic material
• core
• cytoplasm

How does a virus cause a person to develop the common cold?

• invades the host cell to reproduce
• removes energy from the host cell
• produces toxins in the host cell
• protects the host cell from bacteria

Needs host cell to reproduce.

• Virus
• Bacteria
• Fungus
• Protozoan

Viruses are...

• prokaryotic
• eukaryotic
• non-living
• endospores

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

• lytic
• mitosis
• lysogenic
• S phase

A pathogen is

• Any foreign substance that causes an immune response in your body

• A protein that flags an invading bacteria in your body

• A genetic pathway

• The cell that engulfs and destroys invaders in your body

Which of the following occurs right after a virus attaches to a host cell in the viral reproduction process?

• The host cell dies
• The virus dies
• The virus inserts its genetic information into the host cell
• copies of the virus are immediately released from the host

A virus infects a host in order to:

• Take Nutrients

• Make the host sick

• Make copies of itself

• Destroy the host cells

The Lytic cycle consists of......

• Using a host cell to manufacture more candy; rainbows burst out of the cell

• Using a host cell to manufacture more viruses; viruses burst out of the cell

• Not using a host cell to manufacture more viruses; infecting it from within remaining dormant until it is triggered.

• Incorporating the viral genome (DNA) into the host genome (DNA) infecting it from within remaining dormant until it is triggered.
