Viral Replication and Transcription Flashcards
1
Q
How do DNA viruses (Hepatitis, Herpes) achieve this?
A
They can use the host DNA
DNA dependent DNA polymerase
DNA dependent RNA polymerase
2
Q
How do +SSRNA viruses (Norovirus, retroviruses) achieve this?
A
The RNA can act as mRNA so translated directly and these proteins are then used to replicate the original
Or
Via reverse transcriptase to make DNA
3
Q
How do -SSRNA viruses (influenza) achieve this?
A
They have their own enzymes to make +ve RNA and uses this
4
Q
How do DSRNA viruses (Rotoviruses) do this?
A
Use own enzymes to make negative into positive when then use host material
5
Q
Example of DNA virus
A
Hep, Herp
6
Q
Example of SSRNA
A
+ Norovirus and retro
- Influenza
7
Q
DS RNA
A
Rotovirus
