Here's why:

* DNA Structure: DNA is a double helix made up of nucleotides. Each nucleotide consists of three parts:

* Deoxyribose sugar: A five-carbon sugar that forms the backbone of the DNA molecule.

* Phosphate group: Attached to the deoxyribose sugar, providing the molecule with its negative charge.

* Nitrogenous base: One of four different molecules (adenine, guanine, cytosine, or thymine) that carries genetic information.
