The chemical bonds that hold the two strands of DNA together are hydrogen bonds.

  • Deoxyribonucleic acid (DNA) is a double helix composed of two long chains of nucleotides linked together via hydrogen bonds.

  • In DNA, there are four different classes of nucleotides, each one containing one different nitrogenous base (i.e., Adenine, Thymine, Guanine and Cytosine).

  • According to the base pair rules, Adenine always pairs with Thymine via two hydrogen bonds, whereas Cytosine always pairs with Guanine via three hydrogen bonds.

In conclusion, the chemical bonds that hold the two strands of DNA together are hydrogen bonds.
