    Phosphates are bonded to sugars and sugars are bonded to nitrogen bases with covalent bonds.  Nitrogen bases are bonded together across the center of the helix with hydrogen bonds.. sugar-phosphate backbone is held together with covalent bonds. _ Forms a double-helix with complementary base pairings via hydrogen bonds

    Source(s): covalent bonds. _

      There is indeed a Hydrogen bond in the DNA but it is between the two strands of the double helix.  It is between the base of one strand and the base of second strand
