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

Question

Quizplus · Accepted Answer

Chaperone molecules, also known as molecular chaperones, assist in the folding of a polypeptide chain into its functional three-dimensional shape. They can also prevent premature or incorrect folding, as well as assist in the assembly and disassembly of protein complexes. Examples of chaperones include Hsp70 and chaperonin. Spliceosomes are involved in RNA splicing, ubiquitin is involved in protein degradation, and centrosomes are involved in cell division.
