Cryo-EM 3D reconstruction of the CtenRNAV-II capsid. The capsid is viewed down the three-fold axis and radially colored from blue to red corresponding to 125 Å and 165 Å from the center. (A) The complete CtenRNAV-II particle with the icosahedral five-fold, three-fold, and two-fold axes labeled as 5, 3, and 2, respectively. (B) The front half of the CtenRNAV-II particle removed to visualize the inside of the capsid. (C) A thin slice of the central section of the CtenRNAV-II particle.
