Parvovirus properties
+/- ssDNA linear
no envelope
Icosahedral
ex Human parvovirus B-19
hepadnavirus characteristics
circular dsDNA with ss portions
enveloped
unknown capsid
ex Hep B
polyomaviridae characteristics
circular dsDNA
nonenveloped
icosahedral
ex JC virus
papillomaviridae characteristics
circular dsDNA
nonenveloped
icosahedral
ex HPV
adenoviridae characteristics
linear dsDNA
nonenveloped
icosahedral
ex human adenovirus
Herpesviridae characteristics
linear dsDNA
stimulates cell growth, encodes its own polymerase and enzymes to provide deoxyribonuc for DNA synthesis, establishes latent infection in host
enveloped
icosahedral
ex herpes simplex virus
poxviridae characteristics
linear dsDNA with covalently closed ends
encodes it own polymerases and enzymes to provide deoxyribonuc for DNA synthesis, replication machinery and transcription machinery in cytoplasm
enveloped
ovoid
ex vaccinia virus
