DNA nucleotide is composed of three components:

1. A nitrogenous base (which can be adenine, thymine, cytosine, or guanine).
2. A sugar molecule (specifically deoxyribose in DNA).
3. A phosphate group.

The combination of these three components forms a nucleotide, the building block of DNA. The sugar and phosphate groups create the backbone of the DNA strand, while the nitrogenous bases pair up through hydrogen bonds to form the steps of the double helix structure. This structural arrangement is fundamental to the storage and transmission of genetic information in living organisms.
