What is DNA made of?

DNA, short for deoxyribonucleic acid, is the genetic material found in all living organisms. It is made up of a long sequence of smaller units called nucleotides. Each nucleotide is composed of a sugar molecule called deoxyribose, a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), or guanine (G). These nitrogeneous bases are the key to DNA's structure as they pair up - A with T and C with G - to form the famous double helix structure. The order and sequence of these nucleotides determine the genetic information stored in DNA and serve as instructions for the development, functioning, and reproduction of all living organisms.
