DNA, or deoxyribonucleic acid, is the molecular blueprint of life, carrying the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses. Composed of a double helix structure made of nucleotide bases—adenine (A), thymine (T), cytosine (C), and guanine (G)—DNA encodes the information needed to build and maintain an organism. Scientific advances in DNA research continue to revolutionize fields such as medicine, genetics, forensics, and evolutionary biology, making it a central focus of cutting-edge studies and breakthroughs in science.
