DNA contains four nucleotide bases, which are adenine, thymine, cytosine and guanine. The pairs of nucleotides that can be held together by weak hydrogen bonds are purines and pyrimidines.
DNA is held together by hydrogen bonds. So most likely i believe that nucleotides are held together by these bonds because DNA consists of two nucleotides

Phophodiester bonds are the one that connect the nucleotides next to each other on the same strand. Weak hydrogen bonds join the two complementary nucleotides and thus the two strands of the DNA together.
DNA base pairs are held together by Hydrogen Bonds. Adenine and Thymine have 2 bonds that hold them together while Cysteine and Guanine have 3 bonds that hold them together. The hydrogen bonds generally occur between a Nitrogen and a carbonyl oxygen.
Between nucleotides, there is a phosphodiester bond between the phosphate group of one nucleotide and the sugar of another nucleotide. Nucleotides (such as Adenine and Thymine) are held together on two strands of DNA through hydrogen bonding. This doesn't keep nucleotides together in a strand, but helps in the structure of two corresponding strands of DNA.
Hydrogen Bonds
Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.
Through covalent and hydrogen bonds. The covalent bonds hold the pentose sugar-phosphate backbone together and are alternatively called phosphodiester bonds. The hydrogen bonds are between the nitrogen bases and hold the "rungs" of the ladder together.
The base pairs are held together by hydrogen bonds.
The backbone of the nucleotides are composed of repeating ribose (in RNA) or deoxyribose (in DNA) and phosphates held together by phosphodiester bonds between the 5's and 3's of the ribose/deoxyribose.
In producing a strand of DNA the nucleotides combine to form phosphodiester bonds.
Phophodiester bonds are the one that connect the nucleotides next to each other on the same strand. Weak hydrogen bonds join the two complementary nucleotides and thus the two strands of the DNA together.
I just did this paper in Biology, the answer is Hydrogen bonds! :)

Hydrogen bonds are weak, but they are able to hold the backbones together. If covalent bonds held the templates together instead, the bonds would be even weaker and would likely break.
