SARS virus (Part of 2A) Flashcards
1
Q
Genome is the (2)
A
+sense
single stranded rna
2
Q
What happens first
A
Sars S1 protein binds with ACE prptein of host cell then membrane fuses and sars cell content comes in
3
Q
what happens after rna genome is dumped
A
Host cell ribosomes translate the genome into proteins that include rna polymerase for rna replication.
4
Q
RDRP
A
synthesizes -sense strand ssRNA for viral transcription and replication. Does not read off DNA strand reads off +sense strand
5
Q
+sense/-sense
A
Make a bunch of -sense and then +sense and you can make a whole bunch of proteins.
6
Q
Sars is in which cycle?
A
lytic
since it doesnt integrate genome into host genome
7
Q
How are they released?
A
exocytocsis
