Publisher Summary The inference of phylogenetic relationships from molecular data is
contributing greatly in understanding the evolution of life on Earth. Although the discussion …

As molecular phylogeny increasingly shapes our understanding of organismal relationships,
no molecule has been applied to more questions than have ribosomal RNAs. We review this …

Ribosomal DNA (rDNA) sequences have been aligned and compared in a number of living
organisms, and this approach has provided a wealth of information about phylogenetic …

Comparisons of macromolecular sequences offer the greatest potential for inferring
phylogenetic relationships spanning the diversity of extant life (Zuckerkandl and Pauling …

Although the applicability of small subunit ribosomal RNA (16S rRNA) sequences for
bacterial classification is now well accepted, the general use of these molecules has been …

From comparative analyses of the nucleotide sequences of genes encoding ribosomal
RNAs and several proteins, molecular phylogeneticists have constructed a “universal tree of …

Phylogenetic trees among eukaryotic kingdoms were inferred for large-and small-subunit
rRNAs by using a maximum-likelihood method developed by Felsenstein. Although …

Using sequence data from the 28S ribosomal RNA (rRNA) genes of selected vertebrates, we
investigated the effects that constraints imposed by secondary structure have on the …

laboratories, usually display a very simil Page 1 [16] PATHOGEN IDENTIFICATION USING …

Despite the availability of a rapidly growing ribosomal RNA database that now includes
organisms in all three primary lines of descent (eubacteria, archaebacteria, and eukaryotes) …
