The nitrogen bases bond A-T and C-G via hydrogen bonds. The bases are held together in the string by a backbone of alternating phosphate and sugar molecules.

DNA strands are held together by hydrogen bonds that form between the nitrogen bases of both strands.

The two strands of DNA are held together by hydrogen bonds between the pairs of nitrogen bases. The two strands of DNA are not covalently bonded.

Nitrogenous base pairs (adenine, thymine, cytosine, and guanine) are held together by hydrogen bonds. They are held to each other by the backbone of the double helix structure of DNA.

The backbone of the DNA molecule is composed of alternating deoxyribose sugars and phosphate groups. The nitrogen bases are bonded to the sugar molecules. The two strands of DNA are held together by hydrogen bonds between the nitrogen bases of both strands.

Covalent bonding holds the phosphate and deoxyribose together, while the adjacent nitrogen bases are held by hydrogen bond.

Nitrogenous bases.That would be hydrogen bonds.

The bases in DNA are held together with 2 or 3 hydrogen bonds. The bases A and T pair together and C and G pair together.

If you mean the rungs of the twisted ladder model, they are made of the nitrogen bases of both strands held together by hydrogen bonds.

In DNA replication, the nitrogen bases adenine and thymine, and guanine and cytosine form base pairs. The base-pairing rule states that in DNA adenine pairs with thymine and guanine pairs with cytosine, and in RNA adenine pairs with uracil. The paired nitrogen bases are held together with hydrogen bonds.

The rungs of the DNA "ladder" are pairs of 4 types of nitrogen bases: thymines, adenines, guanines, and cytosines, held together by phosphodiester bonds.

Hydrogen bonds between the paired nitrogen bases hold the two strands of DNA together.

By nitrogen bases, do you mean the nitrogenous bases in DNA? If so, do you mean, what bonds are inside the bases, or what bonds hold pairs of these bases together in DNA? The bases themselves are constructed out of covalent bonds, but it is Hydrogen Bonding that holds pairs of these bases together. Hydrogen Bonds, despite their name, are not bonds like covalent bonds, but are a kind of intermolecular interaction that holds the nitrogenous bases of DNA together.
