    Both DNA and RNA found in
    a) Bacteria
    b) Prion
    c) Viriod
    d) Plasmid

    Answer: Bacteria

    1. A plasmid is a small, circular, double-stranded
    DNA molecule that is distinct from a cell’s
    chromosomal DNA. Plasmids naturally exist in
    bacterial cells, and they also occur in some
    2. Viroids are plant pathogens that consist of a
    short stretch of highly complementary, circular,
    single-stranded RNA.
    3. A prion is an infectious agent composed of
    protein in a mis-folded form. Prion diseases or
    transmissible spongiform encephalopathies
    (TSEs) are a family of rare progressive
    neurodegenerative disorders that affect both
    humans and animals.
