Vedclass · Answer

(C) Water plays a critical role in the structural stability of macromolecules like $Proteins$ and $Nucleic$ $acids$.In $Proteins$,the hydrophobic effect drives the folding of the polypeptide chain,where hydrophobic amino acids are buried in the interior,away from the aqueous environment.In $Nucleic$ $acids$ ($DNA$ and $RNA$),water molecules interact with the phosphate backbone and the nitrogenous bases,stabilizing the double-helical structure through hydrogen bonding and hydration shells.Therefore,the correct option is $C$.
