Which term describes a very large molecule built from smaller units?

Explanation:
A macromolecule is the term for a very large molecule built from smaller subunits (monomers) linked together. In biology, these giant polymers include proteins, nucleic acids, and polysaccharides, each formed by joining many monomers such as amino acids, nucleotides, or sugar units. This general category captures the idea of size and polymeric structure, which is why it’s the best fit here. A nucleotide is just a single monomer, a disaccharide is only two sugar units, and while a polysaccharide is indeed a large molecule, it’s a specific type of macromolecule rather than the broad term that describes all such giant polymers.
