Viruses and Bacteria

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

What part of the phage is the DNA?

• A
• B
• C
• D

A(n) _____ is a virus that enters a bacterial cell.

• endospore
• decomposer
• plasmid
• bacteriophage

Antibiotics kill viruses

• True
• False

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

• tail
• nucleus
• capsid
• glycoprotein

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

• lytic
• mitosis
• lysogenic
• S phase

Which viral life cycle kills its host cell by lysing?

• lytic
• mitosis
• lysogenic
• S phase

What do viruses need to reproduce?

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

What happens in the lysogenic cycle? 

• Virus goes in and leaves the host cell
• Virus quickly kills the host cell
• Virus inject the nucleic acid into the host cell, and the nucleic acid integrates into the host cell DNA, and stay dormant for a long time
• Bacteria injects DNA into a host cell

What happens in the lytic cyle?

• Virus goes in and leaves the host cell
• Virus quickly kills the host cell
• Virus sleeps inside of the host cell
• Virus stay dormant for a long time
