A DNA nucleotide contains:
-- a sugar called deoxyribose
-- a phosphate
-- a nitrogen base which is one of four possibilities: adenine, thymine, cytosine, guanine

DNA is deoxyribonucleic acid. The "deoxyribo-" part refers to the five member carbon sugar which lacks a 2'OH group. "Nucleic" refers to the nitrogenous base that hangs off the 1'carbon of this same sugar. The bases can be classified into two groups: purines (A,G) or pyrimidines (C,T). And the "acid" part basically indicates that a phosphate group is attached to the 5' carbon. Nucleotides are not present in DNA; they make up RNA (ribonucleic acid). Deoxnucleotides make up DNA.

a nucleotide has nitrogenous bases(adenine, guanine, cytosine and thymine in DNA/uracil in RNA) attached to a backbone of ribose sugar(C5 H10 O5- RNA and C5 H10 O4- DNA) and phosphate.
they are named as nucleotide mono phosphates.

1) sugar (ribose, in the case of RNA and deoxyribose in the case of DNA); 2) Phosphate group; 3) Nitrogenous Base (Adenine, Guanine, Cytosine, and Thymine (or Uracil)).

You could have googled this faster than I could type it haha. It consists of a 5 carbon sugar: ribose, a nitrogenous base (either uracil, adenine, cytosine, or guanine), and a phosphate group
