virology Flashcards
1
Q
virus components
A
genome
capsid
protein capsid
envelope protein
virus envelope
2
Q
role of protein capsid
A
protects genome from environemnt
delivers genome to cell
3
Q
what does the envelope consis t of
A
lipid bilayer containing viral proteins
4
Q
growth of virus
A
- Virus becomes attached to target cell
- Cell engulfs the virus via endocytosis
- Viral contents are released
- Viral RNA enters the nucleus
- Viral RNA replicated by viral RNA polymerase
- New phage particles are assembled
- New viral particles made
- Released into extracellular fluid
Cell not killed in the process continues to make new virus

PCR
A
amplifciation of part of gene

Q
MLST
A
entire genome sequencing
