Answer: Phosphodiester bond
Explanation:
The backbone of DNA consists of deoxyribose nucleotides linked by phosphodiester bridges.
The 3'-hydroxyl of the adjacent sugar of one deoxyribonucleotide is joined to the 5'-hydroxyl of the adjacent sugar by an internucleotide linkage called a phosphodiester bond.
Thus, phosphodiester bond is the answer
