Question
Chapter 6, Problem 17E
Summary Introduction
To explain: The reason why the Alzheimer’s prone mice displayed the symptoms of the prion disease much sooner than did the normal mice.
Concept introduction: The mis-folded proteins which are associated with neurodegenerative diseases are called prions. It is the harmless protein in abnormal form that is found in the brain. Alzheimer is a chronic neurodegenerative disorder. It leads to the decline in mental function and leads to dementia.
