What is the monomer is not correctly matched wih its macromolcule?

A common example of a monomer that is not correctly matched with its macromolecule is nucleotide and protein. Nucleotides are the monomers that make up nucleic acids like DNA and RNA, while amino acids are the monomers that form proteins. This mismatch highlights the distinct building blocks that are specific to each type of macromolecule.
