Various feature <strong>of</strong> <strong>viruses</strong> can be<br />
estimated by studying:<br />
• Chemical & biochemical studies<br />
• Size <strong>of</strong> particles<br />
• Hydrodynamics<br />
• Laser scattering has been used to determine the<br />
radii <strong>of</strong> spherical <strong>viruses</strong><br />
• E.M.<br />
• X-ray crystallography<br />
• it gives accurate estimates <strong>of</strong> radius <strong>of</strong> icosahedral<br />
<strong>viruses</strong> but condition is that the virus should be able to<br />
form stable crystals.
