The U2 RNA analogue of Trypanosoma brucei gambiense: implications for a splicing mechanism in trypanosomes.

abstract：:With discovery of diverse roles for RNA, its centrality in cellular functions has become increasingly apparent. A number of algorithms have been developed to predict RNA secondary structure. Their performance has been benchmarked by comparing structure predictions to reference secondary structures. Generally, algorith...
