Question
Chapter 4, Problem 54RE
Interpretation Introduction
Interpretation:
The difference in the protein secondary structures between normal and infectious prion is to be determined.
Concept introduction:
Prions are defined as the misfolded proteins that basically characterize several fatal neurodegenerative diseases in animals as well as in humans.
They are even smaller than viruses and do not have
A normal and abnormal prion differs in protein structure.
