We present electron microscopic and X-ray diffraction evidence concerning the structural organization of condensed DNA within a series of T4 bacteriophage with the following head morphologies: prolate (wild-type), isometric and giant (with greatly increased axial ratio). In all cases, the DNA helix segments are locally parallel and 27 A apart. For the giant(More)
The three-dimensional structure of DNA-filled, bacteriophage T4 isometric capsids has been determined by means of cryoelectron microscopy and image reconstruction techniques. The packing geometry of protein subunits on the capsid surface was confirmed to be that of the triangulation class T = 13. The reconstruction clearly shows pentamers, attributed to(More)
