RNA today. Molecular Evolution of Introns and Other RNA Elements: a Keystone Symposium, Taos, NM, USA, February 2-8, 1991.

RNA research is alive and well. The joyride for those studying the biochemistry and molecular biology of RNA continues, although perhaps not at the thrill-a-month pace of recent years. The Keystone Symposium provided an opportunity to gain deeper insight into RNA-based biological phenomena by attempting to place current research in an evolutionary context. In this sense the meeting was an unqualified success. The meeting participants, having been warmed by the New Mexico sun and the chile-laden cuisine, now return to their laboratories determined to pursue not only the details of RNA biochemistry and molecular biology, but also the evolutionary implications of their work.
