Figure 1

High-resolution electron micrograph (A) and scale diagram (B) of bacteriophage 7-7-1. A 14-nm collar connects the icosahedral head with the contractile tail that exhibits a surface structure of helical rows running at an angle of 50°. Five 16-nm tail fibers with splayed tips probably lead the phage along the flagellar filament to the cell surface, where they act as specific adsorption organelles that attach the phage to its final receptor. Details of the tail fine structure were uncovered by optical diffraction [8] of highly resolved electron micrographs.
