Example sentences for: rrna-based

How can you use “rrna-based” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • The major bacterial lineages are poorly resolved in rRNA-based trees [ 2 29 ] and those built using alignments of RNA polymerase subunits [ 30 ] and translation elongation factors [ 29 31 ] . In the currently accepted taxonomy, which is based primarily (but not exclusively) on 16S RNA phylogenetic analysis, bacterial lineages that are suggested by this analysis to form higher-level clusters, tend to form primary nodes under Bacteria (Chlamydiales, Spirochetales, Cyanobacteria, the Thermus-Deinococcus group, Aquificales, Thermotogales).

  • One of their first and most significant findings was the discovery of the third kingdom of life, the Archaebacteria (later renamed Archaea) [ 2 3 4 ] . Subsequently, the analysis of ribosomal RNA produced the first phylogenetic tree, based on the analysis of a single molecule, that included prokaryotes, protozoa, fungi, plants, and animals [ 4 ] . These accomplishments were the foundation for the subsequent revolution in rRNA-based phylogenetic analysis, which has resulted in the sequencing of more than 10,000 16S and 16S-like rRNA and 1,000 23S and 23S-like rRNA genes, from laboratories trying to resolve the phylogenetic relationships for organisms that occupy different sections of the big phylogenetic tree.

  • Recent studies suggest that HGT events may have been much more widespread during prokaryotic evolution than had been previously thought, with genetic exchange even occurring between Bacteria and Archaea [ 35 36 37 ] . While we see no evidence of cross-domain transfer of arsC genes, a number of HGT events could explain some of the discrepancies between 16S rRNA-based and arsC -based phylogenies.
