DNA is deoxyribonucleic acid. It is located in the nuclei of cells, which make up the body. Consequently, DNA can be considered as one of the building blocks of the body.
To understand the exact structure and function of the body it is essential to know what a cell is and how it is structured.
Where is DNA found?

Adenine (A)
Guanine (G)
