[{'content': 'All of the following statements are true about chaperones except that they \nSelect and explain. \nA. Belong to heat shock proteins, B. Are also known as stress proteins, C. Paicipate in protein folding, D. Bind to the hydrophilic regions of an extended polypeptide', 'role': 'user'}, {'content': 'Answer: D \nExplanation: Protein folding requires a specialized group of proteins,refered as chaperones. Chaperones are also known as "heat-shock proteins" and "stress proteins" Chaperones bind to the hydrophobic regions of an extended polypeptide and are impoant in keeping the protein unfolded,until its synthesis is completed.
