B&B: Viral Structure Flashcards
Enveloped
Hep B
Herpes
HIV
Naked
Adenovirus
Rotavirus
Rhinovirus
Hep A/E
All naked viruses are
icosahedral (stable)
Enveloped viruses
icosahedral or helical
Envelope viruses are not transported via
fecal-oral route (requires survival for long period outside body)
Single stranded and linear
Most viruses
ds RNA virus
Reovirus
2 single strands (diploid)
Retroviruses
RNA viruses with circular genome
BAD:
Bunyavirus
Arenavirus
Hep D Virus
RNA viruses that replicate in nucleus
Influenza, Retroviruses
(+) RNA
5’ to 3’
(-) RNA
3’ to 5’
Requires its own RNA polymerase for protein synthesis
Transcription
Make RNA from DNA
DNA-dependent RNA polymerase
Viruses
Make RNA from RNA
Must synthesize their own enzyme
RNA-dependent RNA polymerase
Retroviruses
HIV, HTLV
Retroviruses
2 strand (+) RNA Carry reverse transcriptase enzyme to make dsDNA
Double Stranded
DNA viruses
Single Stranded DNA Virus
Parvo Virus
Viruses with segmented genomes
