उत्तर
In a DNA strand the nucleotides are linked together by phosphodiester bonds.
Explanation:-
A phosphodiester bond is created between the 5' phosphate group of one nucleotide and the 3'-OH group of another when nucleotides are integrated into DNA.
Each strand of DNA has a phosphate-sugar-phosphate-sugar-phosphate "backbone" in this fashion.
