Morgarella [4.7K]

Answer:

3' OH ( hydroxyl group).

Explanation:

DNA is present as the genetic material in almost all the living organisms except in case of some viruses only. DNA is made of the polymers of the nucleotides.

The phosphodiester bond is present between the two nucleotide chains. The phosphodiester is a covalent bond formed in which the phosphate group of nucleotide is involved with the hydroxyl group of the sugar and a small molecule like water is removed during the process.

Thus, the correct answer is  3' OH ( hydroxyl group).
