Question

Quizplus · Accepted Answer

Prions are misfolded versions of normal brain protein. When prions come into contact with normal brain protein, they can cause it to misfold as well, leading to a chain reaction of misfolded proteins. This can eventually lead to neurological disorders, such as Creutzfeldt-Jakob disease and variant Creutzfeldt-Jakob disease. Prions are unique in that they are not viruses or bacteria, but rather infectious proteins.
