Secondary Structures of rRNAs from All Three Domains of Life
Accurate secondary structures are important for understanding ribosomes, which are extremely large and highly complex. Using 3D structures of ribosomes as input, we have revised and corrected traditional secondary (2°) structures of rRNAs. We identify helices by specific geometric and molecular interaction criteria, not by co-variation. The structural approach allows us to incorporate non-canon...

متن کاملPrimary and secondary structures of Escherichia coli MRE 600 23S ribosomal RNA. Comparison with models of secondary structure for maize chloroplast 23S rRNA and for large portions of mouse and human 16S mitochondrial rRNAs.
We determined 90% of the primary structure of E.coli MRE 600 23S rRNA by applying the sequencing gel technique to products of T1, S1, A and Naja oxiana nuclease digestion. Eight cistron heterogeneities were detected, as well as 16 differences with the published sequence of a 23S rRNA gene of an E.coli K12 strain. The positions of 13 post-transcriptionally modified nucleotides and of single-stra...
متن کاملPrimary and Secondary Tumors of the Sternum
Sternal tumors are very rare and challenging. Secondary sternal tumors are more common than primary tumors. These tumors are usually refractory to chemotherapy and radiotherapy, and surgery is the best choice for their treatment. In this study, we reported the collected data of 15 patients with primary and secondary tumors of the sternum, histological type, as well as kind of resection and reco...
