Figure 6From: Observation of the low frequency vibrational modes of bacteriophage M13 in water by Raman spectroscopyDiagrams of the structure of M13 phage. (a) A molecular model containing 10 α-helix coat proteins forming a cone of the structure. (b) A cross section of the phage composed of α-helix coat proteins. (c) The elastic continuum model of M13; a circular cylinder of outer radius "b" and inner radius "a."Back to article page
