Answer:
Molecular chaperons in the cells helps in protein folding. These are the group of proteins that have functional similarity and they also assist protein folding.
They have the ability to prevent the non specific binding and aggregation by the binding of the non native proteins.
Molecular chaperons helps in recognizing the hydrophobic surfaces of the unfolded proteins because they themselves are hydrophobic in nature and will combine to the hydrophic binding and bonding.
This helps in guiding the protein to folding.
