Hi Madhusudhan, As already mentioned, coot is perfectly adapted. But if you have a pretty long DNA strand, maybe you can design an "artificial" DNA strand with http://structure.usc.edu/make-na/server.html It generated different form of DNA (B, Z and A). You can use your known sequence and creat

Dear all, I have an X-ray diffraction data of a protein-DNA complex at 2.3A resolution. I refined the structure, modeled the protein and the R-free reached to 0.35. I am observing extra density for the bound DNA molecule. As I am solving a protein-DNA complex structure for the first time, 1) Coul
