Prions are

  • A.Viruses that are genetically deficient and so incapable of producing infectious daughter virions
  • B.Infective agents free of protein, with low molecular weight RNA
  • C.Infectious protein particles, lacking detectable nucleic acid
  • D.Extrachromosomal genetic elements

Answer: C

Correct answer: Infectious protein particles, lacking detectable nucleic acid

A prion is an infectious protein with no nucleic acid whatever. It is a misfolded form of a normal cellular protein, and it propagates by inducing the normal form to adopt the same misfolding - the mechanism behind scrapie, BSE and Creutzfeldt-Jakob disease.
