Sidow’s studies rely on the principle that if certain pieces of DNA are solexa (http://www.cd-genomics.com/gene/sequence.htm)retained throughout evolution, they must be important. Things that aren’t conserved by evolution are less likely to be required forillumina sequencing (http://www.cd-genomics.com/gene/sequence.htm) basic functions. “I think the rule is that important stuff stays,” he said.
