A DNA nucleotide is one of two kinds of bases... a pyrimidine or a purine. The purine is a heterocyclic (two-ring) molecule with a 5 member and 6 member ring each containing 2 Nitrogens. Purines are just a single ring with 2 Nitrogens. Each base is paired with a sugar (ribose) less one oxygen (hence the prefix de-oxyribose). Some nucleotides also bear a methyl group. These methylated nucleotides help the body identify self from non-self DNA and also are used in determining which strand is the original strand after duplication for the purpose of DNA repair. There are 4 types of DNA nucleotides. Adenine, Guanine, Thymine, and Cytosine. There are others... but we don't use them often unless a mistake happens or a mutation or tautumeric shift occurs (whole other subject). There are a handful of others.

What macromolecules are made of nucleotides?
RNA and DNA.
What are repeating subunits of DNA and RNA called?
Nucleotides are repeating subunits that make up DNA.
Individual chains of the DNA double helix are made up of molecules called?
nucleotides
What makes up the side of the ''ladder'' of a DNA molecule?
The sides of the DNA latter consist of the sugar deoxyribose and phosphates. The bond between the latter and the nitrogen bases together is known a a nucleotide. Nucleotides are molecules that make up the structure of DNA and RNA.
What is the function of DNA polymerase?
DNA polymerases are the enzymes responsible for joining DNA nucleotides together. In Prokaryotes - DNA Pol III is the enzyme which adds nucleotides to the new strand during DNA replication. DNA Pol I is responsible for replacing the primers with DNA nucleotides.
What are the monomers of DNA made of?
its made up of nucleotides
What does cell makes a mistakes and copy in its DNA?
nucleotides
What compounds are the building blocks of DNA macro-molecules?
Nucleotides are the monomer units that make up a DNA molecule. DNA nucleotides are composed of a deoxyribose sugar, a nitrogenous base, and a phosphate group.
What macromolecules are made of nucleotides?
RNA and DNA.
What are DNA precursors?
dna precursors are the thing that make up dna, nucleotides
What are two larger molecules made up of nucleotides?
DNA and RNA are made up of nucleotides.
What is the name of the nucleotides have no DNA and no RNA?
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
What are precursors?
dna precursors are the thing that make up dna, nucleotides
What makes DNA a polymer?
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.)
How is a gene related to the sequence of nucleotides?
Genes are segments of DNA. DNA is made up of polymer of nucleotides joined together. When there is an alteration in the sequence of nucleotides, gene mutation occurs.
Is the monomers of DNA are nucleic acids?
No, the monomers which make up DNA are nucleotides.
What are subunits making up nucleic acid?
Nucleotides are smaller subunits that make up nucleic acids.
