Question

___________________- is a rapidly fatal neurodegenerative disorder characterized by the accumulation of abnormally shaped infectious prion proteins in neurons.

Answer 1

Prions are small proteins that can cause fatal neurodegenerative disorders characterized by the accumulation of abnormally shaped infectious prion proteins in neurons. Examples include Creutzfeldt-Jakob disease (CJD), mad cow disease, and kuru.

Step-by-step explanation:

Prions are small proteins found in nerve tissue that can cause fatal neurodegenerative disorders characterized by the accumulation of abnormally shaped infectious prion proteins in neurons. These infectious prion proteins, known as PrPsc, stimulate other normal proteins to become misfolded, forming plaques in the brain tissue. This accumulation of rogue proteins leads to brain damage, loss of motor coordination, dementia, and ultimately, death. Examples of prion diseases include Creutzfeldt-Jakob disease (CJD), mad cow disease, and kuru.
