DNA


DNA (Deoxyribonucleic Acid)
is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses. It is composed of two long strands that coil around each other to form a double helix, containing the genetic information necessary for the synthesis of proteins and the regulation of cellular activities. DNA sequences are made up of four nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G), which encode the genetic information in the form of genes
