DNA, or deoxyribonucleic acid, is a type of molecule found in all living things This molecule is responsible for the hereditary characteristics of organisms and is made up of four building blocks called nucleotides. Each nucleotide is composed of a sugar, phosphate, and one of four nitrogenous bases: adenine, thymine, guanine, and cytosine. Through a process called DNA replication, these molecules can replicate themselves in an exact fashion and pass down these identical hereditary characteristics from one generation to the next.
