16s ribosomal rna การใช้

• It is a complex of the 16S ribosomal RNA and 22 ribonucleoproteins.
• It is the eukaryotic nuclear homologue of the mitochondrial 16S ribosomal RNAs.
• It can be identified by 16S ribosomal RNA sequencing, and is associated with bacterial vaginosis.
• Like other members in its family, it has a characteristic 16S ribosomal RNA which consists of 1474 base pairs.
• The 16S ribosomal RNA gene sequences of " Chlamydophila " and " Chlamydia " are close to 95 % identical.
• However, further 16S ribosomal RNA studies put the bacteria into genus " Thermoanaerobacter " and the genus was no longer necessary.
• On 16s ribosomal RNA sequence analyses done by Carl Woese, the three domains of current phylogeny were decided; Bacteria, Archaea and Eukarya.
• Originally described in 2006 by K鋗pfer et al . based on 26 clinical isolates from Belgium that shared 94-95 % homology after 16S ribosomal RNA sequencing.
• This new phylogenetic taxonomy depended on the sequencing of 16S ribosomal RNA, and divided prokaryotes into two evolutionary domains, as part of the three-domain system.
• Additional research has demonstrated that the S1 and S21 proteins, in association with the 3'- end of 16S ribosomal RNA, are involved in the initiation of translation.
• 16S rRNA 16S ribosomal RNA gene in " H . thermophilus " also suggest that they are part of some of the earliest differentiating orders of bacteria termed the Aquificales.
• A cladogram based on sequences of mitochondrial 12S ribosomal RNA, 16S ribosomal RNA and cytochrome-c oxidase I ( COI ) genes showing phylogenic relations of Patellogastropoda by Nakano & Ozawa ( 2007)
• The estimate of the number of species present on skin bacteria has been radically changed by the use of 16S ribosomal RNA to identify bacterial species present on skin samples direct from their genetic material.
• The species was formerly known as " Peptococcus saccharolyticus ", but was reclassified on the basis of 16S ribosomal RNA and biochemical similarity to other members of " Staphylococcus ".
• The study also discovered through sequencing 16S ribosomal RNA encoding genes that the F1 hybrids all have an intestinal microbiome distinct from both parent species but were once reported to be present in some gray wolves.
• At the CSH Symposium and earlier, the unsettling number and diversity of microbes that were being discovered through the powerful tool of PCR-amplification of 16S ribosomal RNA genes was exciting, but confusing interpretations in diverse studies.
• For example, the most common gene to be used for constructing phylogenetic relationships in prokaryotes is the 16S ribosomal RNA gene since its sequences tend to be conserved among members with close phylogenetic distances, but variable enough that differences can be measured.
• An interesting fact that gas chromatography mass spectrometry, 16S ribosomal RNA analysis, omics, and other advanced technologies have made more apparent to humans in recent decades is that microbial colonization is very common even in environments that humans think of as being nearly sterile.
• He is best known for the use of 16S ribosomal RNA-based techniques to study the ecology of bacteria in natural and engineered systems and for the creation and evaluation of programs and policies to promote access to clean water and nutritious food in developing communities.
• The " Butyrivibrio " genus encompasses over 60 strains that were originally confined to the species " Butyrivibrio fibrisolvens " based on their phylogenetic analyses based on 16S ribosomal RNA ( rRNA ) gene sequences has divided the genus " Butyrivibrio " into six families.
