    "The smallest RNA viruses in terms of genome size are the smallest of the retroviruses (eg Rous Sarcoma Virus); genome 3.5 kb, particle diameter 80 nm.

    The smallest DNA viruses are the hepadnaviruses (eg hepatitis B) (3.2 kb, 42

    nm). The parvoviruses have smaller capsids (18-26 nm), but a larger genome

    (5 kb).

    Viroids are infectious agents of plants that are comprised of a single small

    molecule of RNA. They lack a capsid and are not considered to be viruses.

    The smallest DNA bacteriophage is phi X174 which I believe is larger than

    Hepa B. RNA phages typically contain about 4 kb. I don't believe there are

    any plant viruses smaller than what I've noted."

    uh, about nothing. I think it's one-celled.
