The backbone of DNA is held together by covalent bonds. DNA is made up of nucleotides, a sugar (2-deoxyribose) attached to a base and a phosphate group. The backbone consists of alternating phosphate and sugar residues joined together by phosphodiester bonds. Hydrogen bonds are involved in stabilising the helix along with what are called base stacking where the aromatic rings in the bases align to minimise the "free energy" these are essentially short range intermolecular forces and are not usually considered to be "bonds".
Gangnam Style
A phosphodiester bond is the type of bond that is present between phosphorus and oxygen in a DNA molecule. This bond forms between the phosphate group of one nucleotide and the hydroxyl group of another nucleotide, linking the nucleotides together in a DNA backbone.
There are no amino acids in desoxy ribo nucleic acid: its is (desoxy)-ribose (carbohydrate)and nucleic acid not amino!
A phosphodiester bond holds nucleotides together in DNA and RNA molecules. This bond links the 5' carbon of one nucleotide to the 3' carbon of the next nucleotide in the strand.
Hydrogen bonds are the type of bond that keeps the bases paired together in a DNA molecule. These bonds form between the complementary bases adenine-thymine and guanine-cytosine.
Hydrogen bonds do this.

A phosphodiester bond holds the deoxyribose sugar and phosphate group together in a DNA molecule. This bond forms between the 3' carbon of one deoxyribose and the 5' carbon of the adjacent deoxyribose in the DNA backbone.
When mRNA separates from DNA, the bond that is broken is a hydrogen bond.

If you are talking about between the bases of DNA, then it is a Hydrogen bond. A hydrogen bond will break easily for replication when the helicase separates the DNA.
