Base
The nitrogenous base is the component that varies in DNA nucleotides. There are four possible bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases determine the genetic information encoded in the DNA molecule.
The nitrogenous base is what causes variation. The deoxyribose and phosphate group are the same on all nucleotides.

Nucleotide
The sugar in a DNA nucleotide contains one less oxygen atom.
The sugar in a DNA nucleotide contains one less oxygen atom.
A adenine (A) nucleotide will bind to thymine (T) nucleotide in parental DNA through hydrogen bonding.
If one nucleotide is replaced by another, it is called a point mutation. This type of mutation involves a change in a single nucleotide within the DNA sequence.
