Electron microscopy of bacteriophage phi 6 nucleocapsid: two-dimensional image analysis.
Electron micrographs of negatively stained nucleocapsids isolated from intact, wild-type phi 6 bacteriophage revealed three distinct morphological forms. Two-dimensional analysis of electron micrographs of two of these forms and image averaging of all forms are consistent with a dodecahedral structure embodied in the phi 6 nucleocapsid.
