----------------------------------------------------------------------- BIOINFORMATICS COLLOQUIUM School of Computational Sciences George Mason University ----------------------------------------------------------------------- How Thermodynamics and Natural Selection Have Moulded RNA and Protein into Ribosomes David E. Draper Dept. of Chemistry Johns Hopkins University Tuesday, November 9, 2004 4:30 pm Verizon Auditorium, Prince William Campus The translation of genetic information into proteins is mediated by the ribosome, a ubiquitous, large (~2.7 MDaltons) and highly conserved cellular organelle. The ribosome is unusual in that its structure is mostly defined by the large RNA molecules that form its active sites; proteins apparently play a peripheral role in both structure and function. The availability of atomic-level structural information and extensive sequence databases now allows many questions about ribosome structure, function, and evolution to be formulated in precise molecular terms. This talk will describe several ways we have probed the significance of specific RNA-RNA and RNA-protein interactions that hold the ribosome together, using computational, biophysical, and genetic approaches. ---------------------------------------------------------------------- Refreshments are served at 4:00 pm.
