Design and Visualization of DNA/RNA Nanostructures from Branched Oligonucleotides Using Blender Software

Аннотация

Recently, three-dimensional nucleic acid nanostructures have attracted great interest, which have been made available through the DNA origami technique. We have proposed a different way of constructing nucleic acid nanoobjects, namely, template-directed assembly employing branched oligonucleotides as templates and building blocks, which include nonnucleotidic linkers, particularly, branching units for connecting three or more oligonucleotide chains. For the design and 3D modelling of such nanostructures as DNA tetrahedron, DNA cube and DNA fullerene C24, we have used Blender software. As we found, Blender not only allows one to visualize complex DNA and RNA nanostructures, but also helps to choose the parameters for their synthesis.
