New method provides panoramic view of protein-RNA interactions in living cells DNA, it has turned out, isn't all it was cracked up to be. In recent years we learned that the molecule of life, the discovery of the 20th century, did not -- could not -- by itself explain the huge differences in complexity between a human and a worm. Forced to look elsewhere, scientists turned to RNA, a direct yet more complex transcript of DNA. But methodological problems have historically plagued the study of RNA regulation in living cells, limiting not only the accuracy of results but also our understanding of RNA's role in human disease.
