To model the DNA nano structures, 3DNA is a software suite, which can be used for modeling, editing and visualizing complex structures. 3DNA works on the simple and modular assembly of DNA Bricks [1] developed by Yonggang Ke, Luvena Ong, William Shih and Peng Yin, thus offering a better approach to construct 3D nano shapes. Apart from modeling and envisaging shapes, 3DNA also supports an integrated random sequence generator that gives sequences directly against the designed model.
