DNA itself is made up of nucleotides. Nucleotides links with
each other to form a DNA chain. In the process of DNA replication,
parent DNA strand needs to be duplicated. Hence, to make a new
strand of DNA it requires nucleotides.
If we put a comma in that sentence after DNA, the answer is yes,
nucleotides are indeed the monomers of DNA.
As written, the question makes no sense, since "DNA nucleotides"
are not polymers and therefore do not have monomers.
