Question
Infectious proteins are present in:
Options
A.Gemini viruses
B.Prions
C.Viroids
D.Satellite viruses
Solution
Sol.(b) [Key Concept: Prions — Infectious Proteins] PRIONS are infectious proteins — they are the causative agents of spongiform encephalopathies (e.g., Scrapie in sheep, Mad Cow Disease/BSE in cattle, Creutzfeldt-Jakob disease in humans). Prions are misfolded proteins (PrP^Sc) that can induce normal cellular proteins (PrP^C) to misfold. They contain NO nucleic acid (no DNA or RNA). Viroids are infectious RNA molecules (no protein); Gemini viruses and satellite viruses have both protein coat and nucleic acid.
