What biological macromolecule is made up of monomers like the one shown below?

I'm guessing this is, "1.02 Chemistry of Life - Biology 1 V20"? If so the answer is Nucleic acid.

Explanation:

Just like in DNA, RNA is made of monomers called nucleotides. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar called ribose, and a phosphate group. Each nitrogenous base in a nucleotide is attached to a sugar molecule, which is attached to one or more phosphate groups.
