The given figure shows: a normally folded protein [A] and a misfolded protein [B]. What will be correct?
I. Prions are misfolded proteins that have the ability to transmit their misfolded shape onto normal variants of the same protein.
II. Prions cause scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle (commonly known as "mad cow disease") and Creutzfeldt–Jakob disease (CJD) in humans.
| 1. Only I | 2. Only II |
| 3. Both I and II | 4. Neither I nor II |
