One of the major complexities of life is protein folding, which has to be exact to make the protein molecule perform its proper function. And the protein strings are often hundreds of amino acids in length. Exzymes, without which there would be no life, often have many thousands of amino acids. Here are two articles describing the solution to a folding problem, i.e., in an AIDS-virus-like retrovirus.-http://www.physorg.com/news/2011-09-gamers-scientists-molecular-retrovirus-enzyme.html-http://www.sciencedaily.com/releases/2011/09/110918144955.htm-Oak Ridge Natl lab has a new invention to predict folding:-http://www.physorg.com/news/2011-09-unravels-mystery-protein.html
