1. DNA
DNA, or deoxyribonucleic acid, is a molecule that contains the instructions for an organism’s development and characteristics. It is found in the nucleus of cells and is made up of four different types of nucleotides: adenine, thymine, cytosine, and guanine. The sequence of these nucleotides determines the genetic code for an organism.
