Correct Answer: Option A
Explanation
Computational protein structure prediction rests on three foundational assumptions: (1) Thermodynamic hypothesis (Anfinsen, 1973): the native folded state corresponds to the global minimum of Gibbs free energy for the given amino acid sequence under physiological conditions —. (2) Monomeric folding: each polypeptide chain folds independently from its own sequence (applicable to single-domain proteins; chaperone-assisted folding modifies but doesn't contradict this). (3) Reliable potential energy functions: force fields (AMBER, CHARMM, OPLS) can reasonably approximate the contributions of bond stretching, angle bending, torsional potentials, electrostatics (Coulomb), and van der Waals forces to determine the lowest-energy conformation. AlphaFold2 has transformed the field by achieving near-experimental accuracy using deep learning.
