Step 1: Understanding DNA bonds
Phosphodiester bonds (ester bonds) connect the phosphate group to the hydroxyl group of the sugar in DNA.
Hydrogen bonds occur between base pairs (A-T, G-C).
Glycosidic bonds link nitrogenous bases to the sugar.
Peptide bonds are found in proteins, not DNA.
Final Answer:
\[ \text{Ester bond} \]
