QUESTIONS & ANSWERS 2024/2025
Virus - ANSWERSSubmicroscopic particles; obligate intracellular parasites that require living cells to
replicate



Genome - ANSWERSEither RNA or DNA

Capsomere - ANSWERSsubunit of the capsid



Neucleocapsid - ANSWERScapsid with enclosed genome



Viral envelope - ANSWERSA membrane that cloaks the capsid that in turn encloses a viral genome.



Virion - ANSWERSa fully formed virus that is able to establish an infection in a host cell



Viral infection mechanism - ANSWERSAttachment > Penetration > Uncoating > Transcription > Translation
> Assembly > Budding > release
