What Role Do Nucleotides Play in the Structure of DNA?

Nucleotides are the main building blocks of DNA. They are really important for how DNA is put together.

Each nucleotide has three parts:

  • A phosphate group
  • A sugar molecule called deoxyribose
  • A nitrogenous base, which can be adenine, thymine, cytosine, or guanine

These nucleotides link together to form a long chain. This chain twists into a shape known as the DNA double helix.

The nitrogenous bases connect with each other across the two strands. Adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). This pairing helps keep the structure stable.

In short, nucleotides are essential. They help to store genetic information and ensure that DNA stays strong and intact.
