Viruses Warm-Up

All viruses are different, but what are two parts that a virus must have?

• Genetic Information (DNA or RNA)

• a lipid membrane

• a nucleus

• a protein coat

Which viral life cycle kills its host cell by lysing (exploding)?

• lytic

• mitosis

• lysogenic

• S phase

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

• lytic

• mitosis

• lysogenic

• S phase

Protects the genome of a virus. Made out of protein.

• Capsid

• Nucleus

• Glycoproteins (surface markers)

• Nucleic Acids (DNA or RNA)

What is in the center of the virus?

• Nucleic Acids (RNA or DNA)

• Nucleus

• Capsid

• Glycoproteins (surface markers)

Which is smaller?

• bacteria

• virus

• cells

Vaccines are made from

• dead or weakened viruses
• fungi
• allergens
• strong, active viruses

Reasons that viruses are considered to be nonliving is because

• They are not cellular
• They cannot reproduce on their own
• They cannot make proteins
• all of the above

What do viruses need to reproduce?

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

Viruses are considered

• living things

• non-living things

• partially living things
