Solution

B. Western blot.

Scrapie is caused by prions, which are misfolded proteins. The presence of these proteins can be confirmed using a Western blot, a method used to detect specific proteins in a sample.

PCR (Polymerase Chain Reaction) and DNA sequencing are used to detect and analyze nucleic acids (DNA or RNA), not proteins. Therefore, they would not be useful in diagnosing a prion disease like scrapie.

Introduction of specific siRNAs (small interfering RNAs) is a technique used to silence the expression of specific genes. It would not be used to diagnose a disease, but rather to study the function of specific genes or potentially to treat diseases caused by overexpression of a gene.

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
