Actually, there are 4 components. AT-GC; Adenine, Thymine, Guanine, and Cytosine.
means it's an enzyme - so it catalyzes a chemical reaction polymer- means it catalyzes the formation of a polymer DNA- means the polymer whose formation it catalyzes is DNA - DNA is a polynucleotide (a polymer of nucleotides, a million nucleotides strung together)
The monomer of a polynucleotide molecule is called a nucleotide. It consists of three components: a phosphate group, a sugar (deoxyribose in DNA or ribose in RNA), and a nitrogenous base (adenine, thymine, cytosine, guanine in DNA; adenine, uracil, cytosine, guanine in RNA).
The term for a polymer composed of three sugars is a trisaccharide.
The three components that create a DNA nucleotide are a phosphate group, a nitrogenous base [this will be either Adenine, Guanine, Cytosine, or Thymine], and a Sugar [deoxyribose, which is how we get the D in DNA].
DNA is considered a polymer because it is made up of repeating units called nucleotides, which are linked together in a long chain. These nucleotides consist of a sugar molecule, a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). The repetitive nature of these units forms a polymer structure.
DNA is a polymer
DNA is the only polymer in that list. The other 3 options are all individual subunits that could be made into a polymer. Amino acids are the monomers (individual subunits) that up DNA and RNA
DNA
Nucleotides.Both DNA and RNA are nucleic acids, and are polymers of nucleotides. A nucleotide has three components: a pentose (five-carbon sugar), and attached to different parts of it a phosphate group and a nitrogenous base (either a purine or a pyrimidine).The monomers (units) of RNA are ribonucleotides, meaning that the pentose is ribose. The monomers of DNA are deoxyribonucleotides, because their sugar is deoxyribose.The nucleotides in a nucleic acid are not all identical. There are four kinds in each nucleic acid, differing only in their bases. The bases in the nucleotides of RNA are cytosine, uracil, adenine, and guanine. Those in DNA are nearly the same, but in place of uracil is thymine.

Base pairs, histones and phosphate bonds
An organic polymer.
A nucleotide is a single structural unit of DNA. If two or more nucleotides are combined together by a polymerase enzyme, the resulting molecule is a polymer. RNA is also composed of nucleotides and can be formed into polymers.
The monomer of a polynucleotide molecule is called a nucleotide. It consists of three components: a phosphate group, a sugar (deoxyribose in DNA or ribose in RNA), and a nitrogenous base (adenine, thymine, cytosine, guanine in DNA; adenine, uracil, cytosine, guanine in RNA).
Polymer: DNA, Monomer: nucleotides Polymer: Proteins, Monomer: amino acids Polymer: Polysaccharides, Monomer: monosaccharides
DNA is a polymer because it is made of up of monomers of nucleotides that differ from each other by their bases. (Adenine, Guanine, Cytosine, and Thymine.)
DNA constantly undergoes changes. It interacts with proteins that are able to replicate and transcribe it to generate a copy of RNA. Inactive sites are changed to active sites and active sites are silenced. DNA can therefore be considered an active polymer
