Assess advanced understanding of protein folding energy landscapes and kinetic pathways, including free-energy surfaces (minima, barriers, transition states), folding/unfolding rate theories, pathway heterogeneity and intermediates, misfolding and aggregation mechanisms; require interpretation of energy diagrams and experimental/computational data (φ-value analysis, single-molecule FRET, MD simulations, Markov state models) and prediction of how mutations, chaperones, or environmental changes alter kinetics and misfolding propensity.
