DNA is a polymer formed by joining nucleotides into long strands to form what?

Explanation:
DNA is a polymer formed by joining nucleotides into long strands called polynucleotides. Each nucleotide links through phosphodiester bonds to create a continuous chain, so the overall molecule is a polynucleotide. A single nucleotide is a mononucleotide, not a polymer, so it doesn’t describe the full DNA molecule. Proteins are built from amino acids, and lipids are not built from nucleotides, so they don’t fit the description of a polymer of nucleotides.
