Virology Pre-Class Quiz

What is a virus?

• A cellular organism that can replicate on its own

• An acellular infectious agent that requires a host cell to replicate

• A type of bacteria with a protein coat

• A parasitic organism with a nucleus

Which of the following best describes the structure of a virus?

• Cell membrane, cytoplasm, and nucleus

• Protein coat (capsid) surrounding nucleic acid

• Ribosomes and mitochondria for energy production

• A lipid bilayer without genetic material

Which genetic materials can be found in viruses?

• Only DNA

• Only RNA

• Both DNA and RNA simultaneously

• Either DNA or RNA, but not both

What is the primary function of the viral capsid?

• To store energy for viral replication

• To facilitate viral movement

• To protect viral genetic material

• To produce viral proteins

Which of the following steps occurs first in the viral replication cycle?

• Assembly of new viral particles

• Entry of viral genetic material into the host cell

• Attachment of the virus to the host cell

• Release of new virions from the host cell

Which of the following methods is commonly used to detect viral infections?

• Gram staining

• Polymerase chain reaction (PCR)

• Blood glucose testing

• Bacterial culture

What is a viral envelope, and what is its origin?

• A protein shell produced by the virus

• A lipid membrane derived from the host cell membrane

• A double-stranded RNA layer made by the virus

• A carbohydrate coating formed during viral assembly
