Answer:
B) The solvent breaks all non covalent interactions.
Step-by-step explanation:
Proteins re made up of polypeptide chains formed from sequences of amino acids.
To form a polypeptide the amino acid are attached to each other by a covalent peptide bond.
In order to form the 3D conformation, the proteins structure is held together by inter-molecular forces that are non covalent.
Therefore for this study where the scientist wants to study how proteins fold. The solvent used will break all non covalent interaction inorder to observe the refolding process.
