DNA Ribbon Molecular Model

The crystal structure of the synthetic DNA dodecamer d(CpGpCpGpApApTpTpCpGpCpG). The molecule forms slightly more than one complete turn of right-handed double-stranded B helix. The model was built using ChimeraX from X-ray diffraction crystal structure data in the Protein Data Bank (PDB ID 1BNA).
