5. Molecular chaperones bind to unfolded or partially folded polypeptide chains in order to accomplish which of the following?
(A) ensure that improper aggregation of hydrophobic segments does not occur
(B) engulf the protein in order to ensure that the protein is not damaged by heat denaturation
(C) facilitate native folding by exposing hydrophobic segments of the protein as it is synthesized
(D) facilitate aggregation of multiple subunits of a protein during synthesis
(E) All of the above are accomplished by molecular chaperones.
