Deciphering the code of viral geometry
By Peter Weiss, 15:53 PM April 15, 2008
A few years after Francis H. Crick and James D. Watson unveiled the structure of DNA in 1953, they rocked the fledgling field of molecular biology again with a bold notion: Viruses are, in part, structured as crystals are. That idea captivated Donald L.D. Caspar and Aaron Klug, who then systematically applied what they knew about crystal geometry to classify and predict the structures that many viruses might assume. The motif that stood out time and again was a set of symmetries seen in vari...
