'''CRYSTAL STRUCTURE OF A FOUR-STRANDED INTERCALATED DNA: D(C4)'''<br />

==Overview==

The crystal structure of d(C4) solved at 2.3-A resolution reveals a, four-stranded molecule composed of two interdigitated or intercalated, duplexes. The duplexes are held together by hemiprotonated, cytosine-cytosine base pairs and are parallel stranded, but the two, duplexes point in opposite directions. The molecule has a slow, right-handed twist of 12.4 degrees between covalently linked cytosine base, pairs, and the base stacking distance is 3.1 A. This is in general, agreement with the NMR studies. A biological role for DNA in this, conformation is suggested.
