21. The second single stranded DNA virus infecting Archaea is Aeropyrum coil-shaped virus ( ACV ). 22. Although other single-stranded DNA viruses which infect diatoms have been discovered ( " Chaetoceros debilis" 23. Unlike most other DNA viruses , parvoviruses are unable to activate DNA synthesis in host cells. 24. Most DNA viruses assemble in the nucleus while most RNA viruses develop solely in cytoplasm. 25. Both of these taxa are non-enveloped single-stranded DNA viruses . 26. The 102 individuals carried seven distinct families of human DNA viruses ( Figure 4A ). 27. The smallest virus known to humanity, however, is the single-stranded DNA virus Porcine circovirus type 1. 28. This is like chimpanzee stool associated circular virus and unlike any other known circular DNA virus . 29. All known virophages are associated with helpers in the giant DNA virus family " Mimiviridae ". 30. The family " Iridoviridae " is one of the five families of nucleocytoplasmic large DNA viruses .
