List examples of biological macromolecules that rely on hydrogen bonding

DNA, RNA and proteins.

Explanation:

Hydrogen bonds are the most intense type of intermolecular force that occurs between permanent dipoles of molecules, where the positive pole is always hydrogen, and the negative pole can be fluorine, oxygen or nitrogen, because these elements are very electronegative, that is, they attract the electrons of the double bond more strongly and have a negative partial charge.

Hydrogen bonds are very important to maintain the structure and function of many biomolecules, among which we can mention: DNA and RNA (hydrogen bonds unite the nitrogenous bases responsible for the formation of DNA and RNA strands), and proteins ( hydrogen bonds allow proteins to assume their three-dimensional structure.)
