A virus can be classified by its type of

• mitochondria
• chromosomes
• nucleic acid
• carbohydrates

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 kills its host cell by rupturing the cell membrane?

• lytic

• mitosis

• lysogenic

• S phase

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 viral process is this?

• phagocytosis

• lytic cycle

• lysogenic cycle

• formation of antibodies

What viral life cycle is shown here?

• Lysogenic Cycle

• Lytic Cycle

• Binary Fission

• Conjugation

What helps prevent viral diseases?

• Vaccines
• Antibiotics
• Herbal tea
• Gene Therapy

Why do doctors suggest people get a flu vaccine every year?

• Flu viruses replicate more rapidly over time
• Flu viruses can mutate from year to year
• Vaccines are absorbed by the body after a year
• Vaccines get stronger over time

Vaccines

• Prevent people from coming in contact with viruses

• give the immune system a preview of a pathogen

• Prevent all viral infections

• Only work on small children
