  1. T.O. Diener discovered a:
    1. free infectious DNA
    2. infectious protein
    3. bacteriophage
    4. free infectious RNA
Correct Option: D

Theodor O. Diener discovered the Potato Spindle Tuber Viroid (“PSTVd”), the first viroid ever identified, in 1971. PSTVd is a small, circular RNA molecule. Dr. Diener discovered that the pathogen causing potato spindle tuber disease is not a virus, as previously believed, but a much smaller, free RNA molecule.
