Many biological macromolecules are naturally occurring polymers.
Draw one straight line from each biological polymer to the correct description of its monomer.
| Biological polymer | Description of monomer |
|---|---|
| Cellulose | Monomers contain both an amine group and a carboxylic acid group |
| Protein | Monomers are nucleotides containing a sugar, phosphate, and a base |
| DNA | Monomers are hydrocarbon chains containing a carbon-carbon double bond |
| Monomers are glucose molecules |
