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.
