__________ diseases are unique in that they can be transmitted by an infective protein that propagates conformational change of existing molecules without synthesizing entirely new infective molecules.
A) Viral
B) Viroid
C) Bacterial
D) Virion
E) Prion

Question

Quizplus · Accepted Answer

Prion diseases are caused by an abnormal form of a protein, the prion protein (PrP), which can induce normal PrP molecules to adopt the abnormal conformation, leading to the propagation of the disease without the need for new infective molecules to be synthesized. Viral, viroid, and bacterial diseases rely on the synthesis and release of new infective particles for transmission. Virion is another term for a virus particle and does not refer to a disease itself.
