They pair by hydrogen bonds holding them together. Covalent bonds hold the nucleotides together, creating a sugar-phosphate backbone.
DNA organization of Eukaryotes has the nucleic acids A pair with T and C pair with T in a double helix formation. Proteins help keep this all together along with hydrogen bonds holding the subunits of DNA together while covalent (strong) bonds hold the two strands together to make the double helix.
Adenine pairs with Thymine Guanine pairs with Cytosine
There are 7 nitrogen atoms in the base pair A-T.
The base on one strand pair with the base on the other strand, adenine with thymine, and cytosine with guanine, they join together by hydrogen bonds. Parent

The nitrogen bases are held together by hydrogen bonds.

Because their shapes allows them to form together with 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.
Guanine and cytosine because they are held together by three hydrogen bonds while adenine and thymine are held together by 2.
Adenine pairs with Thymine Guanine pairs with Cytosine
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.
There are 7 nitrogen atoms in the base pair A-T.
