The core structure and catalytic regions of rRNA have remained largely unchanged over billions ... These variations have been exploited for phylogenetic analyses and the identification of ...

What have we learned about RNA structure and function ... the 23S, 5S, and 16S rRNAs. In comparison, eukaryotic cells contain two types of rRNA genes that give rise to four rRNA species: the ...

The authors used pyrosequencing of 16S rRNA genes to deeply interrogate community structure (phylotype abundance distribution) and randomly sequenced fecal microbial communities (metagenomics ...
