Emiliano Hardin · Answer 1

The correct answer will be option-E

Explanation:

The structure of DNA revealed by Watson and Crick showed that Two strands of DNA are present in the intertwined state forming helix representing DNA as a double helix.

Each strand of DNA is made up of the monomer unit of DNA called nucleotide where each nucleotide binds to another nucleotide through weak covalent bond called phosphodiester bond.

The phosphodiester bond is formed between the 3'-OH group of one nucleotide to 5' phosphate group of another nucleotide. In this way, the phosphate-sugar molecule forms the backbone of the DNA molecule.

Thus, option-E is the correct answer
