Why Are Viroids Resistant to Nucleases

question 73

Multiple Choice

Why are viroids resistant to nucleases?

• A) Having a circular RNA "genome," they are resistant to most exonucleases (that digest the free ends of RNA or DNA).
• B) Having a circular RNA "genome," with no protein shell, they are resistant to the protein-degrading activities of nucleases.
• C) Nucleases will only digest DNA, not RNA, so viroids are protected.
• D) Viroids have only been identified in plants. Plant nucleases cannot digest RNA.
• E) Viroids are composed of single stranded RNA; nucleases only act on double-stranded molecules.
