Optimized geometries of the (6,5) tube with adsorbed C-mers obtained from different initial wrapping configurations. First column shows the averaged final wrapping angle α of the DNA. Second and third columns correspond to hybrid configurations constructed from the 3 and 4 repeat units long (6,5) nanotube and DNA consisting of 25 (C-25-mer) and 29 (C-29-mer) cytosine bases, respectively. The bottom panel shows 31 and 42 C-mers wrapped along (6,5) tube of 4 units in length.
