hydrogen bonds hold it together
DNA is made of two strands (chains) of DNA nucleotides that are twisted, forming a double helix, often compared to a twisted ladder. The two strands are held together by hydrogen bonds between the nitrogen bases.
Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.
double helix
In molecular biology, the term double helix[1] refers to the structure formed by double-stranded molecules of nucleic acids such as DNA and RNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure, and is a fundamental component in determining its tertiary structure. The term entered popular culture with the publication in 1968 of The Double Helix: A Personal Account of the Discovery of the Structure of DNA, by James Watson.The DNA double helix is a spiral polymer of nucleic acids, held together by nucleotides which base pair together.[2] In B-DNA, the most common double helical structure, the double helix is right-handed with about 10-10.5 nucleotides per turn.[3] The double helix structure of DNA contains a major groove and minor groove, the major groove being wider than the minor groove.[2] Given the difference in widths of the major groove and minor groove, many proteins which bind to DNA do so through the wider major groove.[4]
DNA is put togehter by series of sequence of the nucleotides.
The base pairs are held together by hydrogen bonds.
by the sugars - adenine , thymine , cytosine, and guanine

Hydrogen bonds.
DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. The sequence of nucleotides determines individual hereditary characteristics.

Nitrogenous bases.That would be hydrogen bonds.
The two halves of the DNA double helix are held together by hydrogen bonds.
