WebApr 6, 2024 · Structure of DNA DNA has a specific form, despite seeming to be very thin, lengthy strings under a microscope. It is known as a double helix. The backbone that binds the DNA together is outside the double helix. There are two sets of intertwined backbones. The nucleotides indicated by the letters A, T, C, and G are located between the backbones. WebDNA molecules arrange themselves in a model called the DNA double helix. It’s a 3-D structure that is stored in the nucleus of all cells. Remember that the phosphate and sugar molecules are the backbones of the ladder. The bases (A, G, C, G) form the rungs of the ladder.
