Now that the Human Genome Project is over, it's time for scientists to examine the information produced and pursue related research. Much of the post-HGP focus has fallen on genes, spurring new discussions of how heredity works and causing scientists to look at DNA differently, setting aside the traditional focus on genes as the dominant actors within DNA. Some researchers are now looking at the 99 or so percent of DNA that aren't genes, wondering if these previously neglected chunks of the genome have significant roles to play.
