QUESTION
Molecules that help in correct folding of improperly folded polypeptides are?
OPTIONS
(A) Histones
(B) Chaperones
(C) Amyloid fibres
(D) Protomers
ANSWER
(B) Chaperones
EXPLANATION
Chaperones are the correct option because molecular chaperones assist polypeptides in achieving or regaining their correct three-dimensional folding and can prevent inappropriate aggregation. Histones package DNA, amyloid fibres are aggregated protein structures associated with misfolding, and protomers are individual subunits of larger protein complexes rather than folding assistants.
