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 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.
DNA bases are held together by hydrogen bonds. Adenine pairs with thymine through two hydrogen bonds, while guanine pairs with cytosine through three hydrogen bonds. These interactions contribute to the stability of the DNA double helix structure.
Hydrogen 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.
The two chains of a DNA double helix are held together by hydrogen bonds between complementary base pairs. Adenine pairs with thymine, and cytosine pairs with guanine. These hydrogen bonds form the base pairs that hold the two strands of DNA together.
Nucleic acids are held together by phosphodiester bonds between the sugar and phosphate groups of adjacent nucleotides in the backbone of the molecule. Additionally, hydrogen bonds between nitrogenous bases in complementary strands help stabilize the double-stranded structure of DNA or RNA.
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.
I just did this paper in Biology, the answer is Hydrogen bonds! :)

Adenine and Thymine Guanine and Cytosine held together by hydrogen bonds: 2 for A-T and 3 for G-C
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.
hydrogen bonds
DNA forms a double helix structure due to hydrogen bonds between complementary base pairs. Adenine pairs with thymine, while guanine pairs with cytosine, creating the stable double-stranded DNA molecule.
