A
- Pathogenic
- dsDNA
- Nonenveloped
7
Q
What is an example of papovaviridae?
A
Papillomavirus
- pathogenic
- causes warts
- can transfer cells and cause cancer
8

A
- Pathogenic
- Class 7
- dsDNA
- Enveloped
9
Q
What is an example of hepadnaviridae?
A
Hepatitis B virus
- uses reverse transcriptase to make DNA from RNA
10
Q
In an RNA virus where do viruses multiply?
A
In the host cell’s cytoplasm using RNA-dependent RNA polymerase
11
Q
What are the 2 types of strands in RNA viruses?
A
- ssRNA: + (sense) strand
- ssRNA: - (antisense) strand
- dsRNA: double stranded RNA
12
Q
ssRNA: + (sense) strand
A
Viral RNA serves as mRNA for protein synthesis
13
Q
ssRNA: - (antisense) strand
A
Virla RNA is transcribed to a + strand to serve as mRNA for protein synthesis
14

- Reoviridae
15
Q
Picornaviridae (3)
A
- Pathogenic
- ssRNA + (sense) strand
- Nonenveloped
