Which term describes a molecule that can join to form larger molecules?

• A. Organic
• B. Monomer
• C. Macromolecule
• D. Inorganic

Answer: (B)

The idea here is that small building blocks can link together to create larger biological molecules, and the term for a single unit that can join with others to form those bigger structures is a monomer. A monomer is the basic unit that bonds to form polymers, such as amino acids joining to make proteins or nucleotides building DNA. Organic and inorganic describe types of compounds rather than the role of a unit in linking, and macromolecule refers to the large product formed after many monomers have joined. So monomer is the best fit because it names the individual unit that can connect to build larger molecules.
