Distinguish between the different levels of protein structure, including primary, secondary, tertiary, and Question Prions are a type of protein implicated in bovine spongiform encephalopathy (BSE), also known as "mad cow disease," and related pathologies found in sheep (scrappie) and humans (Creutzfeldt-Jakob disease). The disease occurs when sections of an otherwise healthy protein misfold from alpha-helices to beta-pleated sheets, forming tightly packed sections of beta-pleated sheets that are difficult to break down. The disease propagates because the misfolded prions induce...
