Virus Structure and Function Quiz

Viruses lack cellular structures like cytoplasm.

Envelope aids in host cell attachment.

Capsid encloses viral genetic material.

Bacteriophages specifically infect bacteria.

RNA viruses replicate in the host cytoplasm.

Viral RNA polymerase synthesizes RNA.

Budding is a method of enveloped virus release, not entry.

Viral protease cleaves proteins from polyproteins.

mRNA is a type of cellular, not viral, nucleic acid.

Viral genome's primary role is to replicate itself.

Bacteriophages specifically target bacteria.

Reverse transcriptase converts RNA into DNA.

Neuraminidase helps release viruses from host cells.

Viroids consist of single-stranded RNA.

Retroviruses integrate their genome into the host's.

Enhances attachment specificity in virus-cell interaction.

Prions consist solely of misfolded proteins.

Integrase integrates viral DNA into the host genome.

Satellite viruses rely on other viruses for replication.

Viral receptors influence tissue specificity in infections.

Retroviruses perform reverse transcription.

Viruses acquire envelopes through budding.

Viruses evade immune responses via surface protein mutation.

Viruses can induce host cell apoptosis for exit.

Viral DNA integration into the host genome can lead to cancer.
