8

DNA viruses and cancer?

integrative and transforming potential-- get into host cell DNA and persist, potentially causing cancer

9

Which DNA viruses have circular DNA?

Hepadna and Papova

10

How do naked viruses enter cell? enveloped?

magic + endocytosis; endocytosis + fusion

11

Broad spectrum drugs that affect multiple viruses

amantidine, rimantadine, tromantadine

12

immediate early proteins (alpha)

regulatory and evasive functions-- stop host responses like interferons

13

early proteins (beta)

regulation of cell function and replication of viral genome

14

late proteins (gamma)

structural
