On October 21, 2004, 4:00 PM Barus & Holley (Room 190) Lois Pollack (Cornell University) presented a talk entitled:
"Microfabrication and x-ray scattering: new tools for studying RNA folding"
as part of the Seminar Series
"Frontiers in the Interaction Between Physics and Biology"
Abstract:
Large biological molecules like proteins and RNA, carry out their functions by folding to well-defined three-dimensional structures. We are interested in the physical interactions that direct this self-assembly process. By combining microfabricated flow cells with sychrotron x-ray scattering, we have gained insight into the earliest steps of protein and RNA folding. A recent series of experiments indicates that the critical, first stage of RNA folding is dominated by electrostatic interactions.
