There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

The ribosome grew by accretion of new RNA onto old RNA in a process reminiscent of nested Russian dolls. The most ancient part of the ribosome contains small RNA fragments and is represented by the smallest doll. Ever more recent additions to the ribosome increased its functionality, and are represented on dolls of increasing size. The largest doll represents the ribosomal RNA that is shared by all current forms of life. (Credit: Nick Hud)
