Filaments formed from DNA in complex with small dendrimer molecules
These filaments are formed from multiple DNA molecules tightly weaved with small dendrimer molecules G6. Dendrimers are small positively charged molecules. In different experimental conditions they can form different structures, for example these filaments or bead-on-a-thread-like structures. The height of the filaments is about 2-3 nm, while the hight of a single DNA molecules on this picture is 0.8 nm only.
