Here, we look at how hydrogen bonds in DNA contribute to the overall stability of the DNA double helix structure. slide 1 of 4. Deoxyribonucleic acid, or DNA, is a polymer of nucleotides linked together by specific bonds known as phosphodiester bridges. The phosphate group (PO3) of one nucleotide links to the hydroxyl group (OH) of the following nucleotide. Hundreds of millions of these linkages occur within the DNA polymer.
