Johann Friedrich Miescher discovered DNA in the nineteenth century. He called it nuclein because he found it in the nucleus of a cell. While the term nuclein has fallen into disuse, its influence still persists in the expression “nucleic acid,” which literally means “an acid of nuclein.” Several kinds of nucleic acid occur. Some of them exist outside the cell nucleus. DNA DNA, the substance discovered by Miescher, is deoxyribonucleic acid. Structurally it looks like a ladder that has been twisted slightly, so that it forms a double helix. Two rows of alternating phosphates and simple sugars form the outside framework of this helical ladder. The rungs of the ladder unite with a sugar on each of the two helical strands. Each rung consists of a pair of substances called nitrogen b
