2017 Microbiology - Medical Virology Intro Flashcards
Characteristics of DNA Viruses w/ exceptions
ds, except Parvo
linear, except Papilloma, Polyoma, Hapadna
Icosahedral, except Pox
Replicate in nucleus, except Pox
Characteristics of RNA Viruses w/ exceptions
ss, except Reovirus
if - stranded, capsid carries viral polymerase
All: - stranded viral RNA and dsRNA is non-infectious while most viral DNA is infectious
Replicate in cytoplasm, except influenza and retrovirus

What is required for Transformation? What are the steps?
A competent cell
- Bind DNA
- DNA uptake
- DNA integration
What is transduction?
Transfer of DNA using a virus (bacteriophage)
Recombination follows which events of DNA exchange?
Transformation
Transduction
Conjugation
Which RNA virus shows legitimate recombination?
Picornaviridae
What is a lytic infection?
Terminal, destructive, common type of infection where infection takes place and more virus is produced, cell undergoes lysis and virus spreads.
What is a Lysogenic Infection?
Dormant infection, not actively reproducing
