Here's a breakdown:

* DNA (Deoxyribonucleic Acid) is a long polymer made up of repeating units called nucleotides.

* Nucleotides are the building blocks of DNA. Each nucleotide consists of three components:

* A sugar molecule (deoxyribose in the case of DNA)

* A phosphate group

* A nitrogenous base (adenine, guanine, cytosine, or thymine)

So, to answer your question directly: DNA is made up of nucleotides, which are the macromolecules that make up DNA.
