______ molecules aid in the folding of a polypeptide chain into its secondary or tertiary structure.
A)Spliceosome
B)Ubiquitin
C)Centrosome
D)Chaperone

Question

Quizplus · Accepted Answer

Chaperone molecules, also known as molecular chaperones or heat shock proteins, assist in the folding of a polypeptide chain into its secondary or tertiary structure by preventing improper folding or aggregation. They help to ensure that proteins fold correctly and are essential for proper protein function. Spliceosomes are complexes involved in RNA splicing, ubiquitin is a protein involved in protein degradation, and centrosomes are organelles involved in cell division. None of these are involved in protein folding.
