What make up DNA base

There are four DNA bases: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases pair up with each other to form the double helix structure of DNA. Adenine always pairs with thymine, and cytosine always pairs with guanine.

DNA is made up of four types of nucleotide bases:

1. Adenine (A): It forms a base pair with Thymine (T) in DNA.
2. Thymine (T): It forms a base pair with Adenine (A) in DNA.
3. Guanine (G): It forms a base pair with Cytosine (C) in DNA.
4. Cytosine (C): It forms a base pair with Guanine (G) in DNA.

These four bases combine in specific sequences to form the genetic code that provides instructions for the development, functioning, and reproduction of all living organisms.
