What are the three components of DNA?

The three components of DNA are deoxyribose, phosphoric acid, and nitrogen bases.

Deoxyribose is a five-carbon sugar that forms the backbone of the DNA molecule, linking with phosphate groups and nitrogenous bases to create the overall structure of DNA. Phosphoric acid, or phosphate groups, alternates with deoxyribose to form the sugar-phosphate backbone that provides stability and structure to the DNA molecule. Nitrogen bases (adenine, thymine, cytosine, and guanine) are attached to the deoxyribose sugar and are crucial for encoding genetic information through the sequences in which they appear.

This combination of deoxyribose, phosphoric acid, and nitrogen bases creates the double helix structure known to be characteristic of DNA, allowing it to store and replicate genetic information essential for life.
