Prions are misfield protein molecules, which propagate by transmitting a misfile

Question

Prions are misfield protein molecules, which propagate by transmitting a misfiled protein state. If a prion enters a healthy organism, it induces existing, properly folded proteins to convert into the disease-associated, misfiled prion from; the prion acts as a template to guide the of more proteins into prion form. These newly formed prions can then go on to convert more proteins themselves. Bovine spongiform encephalopathy or "mad cow disease" is caused by prions. Which level of protein structure was NOT affected in Mad Cow Disease? Primary Secondary Tertiary Quaternary all levels were affected

Explanation / Answer

18. ANS: A. primary.

Explanation:

Primary structure was not affected in Mad Cow Disease. Prions are misfolded forms of regular cell proteins with a distinctive ability to convert their normally folded counterparts into more prions. Mad cow disease is an acquired disease from consuming contaminated animal products.
