a. Phosphate group

The hydrophilic nature of DNA is primarily due to the presence of phosphate groups in its structure. DNA is composed of nucleotides, each of which contains a phosphate group, a deoxyribose sugar molecule, and a nitrogenous base (adenine, cytosine, guanine, or thymine). The negatively charged phosphate groups make the DNA molecule hydrophilic, meaning it has an affinity for water and interacts readily with water molecules.
