Explanation:
DNA is a large molecule built up by linking together smaller molecules called nucleotides.
A nucleotide contains a phosphate group, a sugar (deoxyribose in the case of DNA) and a nitrogen base.
The <em>nucleotides are linked together by the binding of</em> the phosphate group on carbon 5 in the nucleotide that is added, and the oxygen of the hydroxyl group (-OH) on carbon 3 of the last nucleotide of the DNA chain.
These bonds are called phosphodiester bonds and their formation releases a molecule of H2O.
This reaction is catalyzed by an enzyme, DNA polymerase, that requires a free 3´ hydroxyl group (3´ OH in the growing chain) to add the new nucleotide.
