| Using mathematical arguments and evidence for icosahedral symmetry in X-ray analyses of various viruses, Caspar and Klug proposed that those viruses referred to as spherical viruses--because under microscopes look like balls--actually have icosahedral symmetry. It had long been known that icosahedral symmetry is not allowed for a periodic object (2). The icosahedral symmetry of the phase was demonstrated by carefully constructing a reciprocal lattice using a series of selected area electron diffraction. |
