Viral Structure Flashcards
- Study of viruses
- Viruses are not considered as living cells as they are independent to a host to survive
Viral Structure
entire virus particle
Virion
either DNA or RNA (can’t be both)
Nucleic acid
protein coat that protects the nucleic acid
Capsid
genome and its protein coat
Nucleocapsid
- lipid-containing
- More susceptible to inactivation by high
temperatures, extreme pH, and chemicals than
nonenveloped (naked) viruses
Envelope
DNA Viruses
Single Stranded
Parvoviridae - common in dog

Double Stranded
Reoviridae – causes diarrhea most
common in children
