24. Example of a DNA virus

25. RNA viruses

27. genome consists of RNA
genome copied by
RNA-dependent
RNA polymerase

28. RdRP is error-prone
producing mutations
that may lead to new
strains

29. Polio Virus

30. Retroviruses

31. genome consists of RNA
RNA turned into DNA
by reverse transcriptase
DNA integrated
into host’s DNA
by integrase

34. Viral Diseases

35. Vectors
disease-bearing organisms

36. Reassortment
when hosts infected with
multiple strains combine
genes from those strains
to produce a new strain
