Which is larger, a polymer or a monomer?

A. Polymer

B. Monomer

B: polymer, Polymer is a greek word which means many pieces (polla meri). By definition it's a macromolecule (long molecule) which has been created by the reaction of many molecules called monomers.

Monomers link together to make polymers. Examples of monomer-polymer pairs:

Monomer: Amino acids

Polymer: Proteins

Monomer: Nucleotide

Polymer: DNA (and RNA)

Monomer: Monosaccaride

Polymer: Polysaccharide

Note the prefixes of these words. Mono - means "one" and poly - means "many". The "ones" (monomers) make up the "many" (polymers).
