Laboratory 'theme park' re-creates RNA world for study
... Bartel's RNA theme park. According to Bartel, the micro
exhibits in his lab are "artificial and fragmented when compared with the real thing, but still well worth a visit." So far, Bartel has developed some impressive displays. In a paper published in the journal Science in 2001, his lab demonstrated one...
