A section of DNA. The bases lie horizontally between the two spiraling strands [15] (animated version). The DNA double helix is stabilized primarily by two forces: hydrogen bonds between nucleotides and base-stacking interactions among aromatic nucleobases. [16] The four bases found in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).
