The joining of nucleotides takes place by a condensation reaction, which discharges a small, stable molecule. Unlike carbohydrates, proteins, and lipids, the molecules, which is discharged is not water, however, a pyrophosphate, that is, two phosphate groups combined together.

In the polymerization of DNA, a phosphodiester bond is formed between a free 5 prime phosphate group at one terminal and a free 3 prime hydroxyl group at the other end. The naming of these sequences is done from 5 prime to 3 prime.
