circular or linear: linear (all are linear except papilloma, polyoma and hepadnovirus)
shape of capsid: icosahedral
enveloped or naked: naked

18
Q

Which DNA viruses would be infectous without their capsid? (naked viral genome infectivity)

Study These Flashcards
A

ALL dsDNA viruses EXCEPT FOR POXVIRUS!!

NOTE: all DNA viruses are ds except parvovirus

19
Q

Are DNA viruses diploid or haploid?

Study These Flashcards
A

ALL ARE HAPLOID!!

20
Q

ALL DNA viruses replicate in the _______ except Poxvirus, which replicates in the ______

Study These Flashcards
A

ALL DNA viruses replicate in the NUCLEUS (they need the host cells machinery) except Poxvirus, which replicates in the CYTOPLASM

21
Q

where does the Poxvirus replicate?

Study These Flashcards
A

in the cytoplasm

22
Q

what is the only DNA virus that doesn’t replicate in the nucleus? Where does it replicate?

Study These Flashcards
A

the Poxvirus replicated in the cytoplasm

23
Q

What are the naked DNA viruses (4)?

Study These Flashcards
A

Papilloma
Adenovirus
Polyomavirus
Parvovirus

Think, the NAKED RNA and DNA viruses are “CPR and PAPPsHmear (with CPR and H being RNA viruses, Calicivirus, Picornavirus, Reovirus and Hepevirus)

24

  2. Herpesvirus
  3. Adenovirus
  4. Poxvirus
  5. Papillomavirus
  6. Polyomavirus
  7. Poxvirus
  8. Parvovirus
25
the only DNA virus that is not icosahedral is
poxvirus
26
All DNA viruses have a capsid that is ______ except the poxvirus
