They pair by hydrogen bonds holding them together. Covalent bonds hold the nucleotides together, creating a sugar-phosphate backbone.
The nitrogen bases of DNA pair up according to specific base-pairing rules: adenine (A) pairs with thymine (T) and guanine (G) pairs with cytosine (C). This base pairing forms the rungs of the DNA ladder structure, with hydrogen bonds holding the pairs together.
The piece holding DNA together is the sugar-phosphate backbone, which consists of alternating sugar (deoxyribose) and phosphate groups. This backbone provides structural stability and support for the DNA molecule. Additionally, the nitrogenous bases (adenine, thymine, cytosine, and guanine) pair with each other through hydrogen bonds, forming the rungs of the DNA double helix and contributing to the molecule's overall integrity.
There are 7 nitrogen atoms in the base pair A-T.
Adenine pairs with Thymine Guanine pairs with Cytosine

The nitrogen bases are held together by hydrogen bonds.
Guanine and cytosine because they are held together by three hydrogen bonds while adenine and thymine are held together by 2.
Because their shapes allows them to form together with hydrogen bonds
Each base pair in DNA is connected by two hydrogen bonds.
As far as I understand, DNA has no ionic bonds. The two 'halves' are bound together by Hydrogen bonds between base-pair amino acids.

The Adenine (Thymine) base pair is held together by 2 hydrogen bonds while the Guanine (Cytosine) base pair is held together by 3 hydrogen bonds. That is also the reason why the two strands of a DNA molecule can be separated more easily at sections that are densely populated by A - T base pairs.
