For 10 points, name this molecule that carries the genetic information of living organisms.
The Hoecht stain binds to the minor groove of this molecule, forming G-quadruplexes. The ratio of nitrogen isotopes in this molecule, which exists in A, B, and Z forms, was measured in the Meselson-Stahl experiment to give evidence for its semiconservative replication. It winds around proteins called histones, and Okazaki fragments are formed when its namesake enzyme travels from the 5-prime to 3-prime direction of this molecule adding nucleotides.
