Virus Structure Flashcards
1
Q
what is a virion
A
a virus particle
2
Q
what components do viruses have
A
ALL viruses have:
1. genome (RNA or DNA)
2. capsid (protects viral genome and mediates attachment to host cell IF cell is naked)
some viruses have an optional ENVELOPE
3
Q
are naked or enveloped viruses more fragile
A
enveloped viruses are more fragile, but they may carry proteins for immune evasion or pathogenesis
4
Q
are viruses with ICOSAHEDRAL capsids naked or enveloped
A
can be either
5
Q
are viruses with HELICAL capsids naked or enveloped
A
MUST be ENVELOPED
6
Q
immunological cloak of invisibility concept
A
enveloped viruses expose relatively few surface proteins, reducing their exposure to the immune system
