Creutzfeldt-Jakob disease, mad cow disease, and scrapie in sheep are diseases caused by infectious particles called .

What is the name of the human variant of "mad cow disease"?

Prions (short for proteinaceous infectious particle) are infectious protein structures that replicate throughconversion of normal host proteins of the same type. Though the exact mechanisms of their actions andreproduction are unknown, it is now commonly accepted that prions are responsible for a number ofpreviously known but little-understood diseases generally classified under transmissible spongiformencephalopathy diseases (TSEs), including scrapie (a disease of sheep), Creutzfeldt-Jakob disease (CJD)and bovine spongiform encephalopathy (BSE or mad cow disease). These diseases affect the structure ofbrain tissue and all are fatal and untreatable.Not all prions are dangerous; in fact, prion-like proteins are found naturally in many (perhaps all) plants andanimals. Because of this, scientists reasoned that such proteins could give some sort of evolutionaryadvantage to their host.6) TSE, BSE and scrapie are all forms of CJD.A. TrueB. FalseC. Can't say
