16S ribosomal RNA - Wikipedia
16 S ribosomal RNA (or 16 S rRNA) is the RNA component of the 30S subunit of a prokaryotic ribosome (SSU rRNA). It binds to the Shine-Dalgarno sequence and provides most of the SSU structure.
Evaluation of 16S rRNA gene sequencing for species and strain …
2019年11月6日 · Here, we use in silico and sequence-based experiments to critically re-evaluate the potential of the 16S gene to provide taxonomic resolution at species and strain level.
16S Ribosomal RNA - an overview | ScienceDirect Topics
16S ribosomal RNA sequences have been used extensively in the classification and identification of Bacteria and Archaea. The comparison of almost complete 16S rRNA gene sequences has been widely used to establish taxonomic relationships between prokaryotic strains, with 98.65% similarity currently recognized as the cutoff for delineating species.

Annotated by 6 databases (SILVA, ENA, Rfam, CRW, PDBe, Modomics). Has a conserved secondary structure or a structured region.
Rapid determination of 16S ribosomal RNA sequences for
The 16S rRNA in bulk cellular RNA preparations is selectively targeted for dideoxynucleotide-terminated sequencing by using reverse transcriptase and synthetic oligodeoxynucleotide primers complementary to universally conserved 16S rRNA sequences.
16S rRNA Gene Sequencing: Principle, Steps, Applications
2024年7月21日 · 16S rRNA gene sequencing is an amplicon-based sequencing method that is used to identify and classify bacteria present in bulk and complex biological samples. This method uses the highly conserved nature of the 16S ribosomal RNA (rRNA) gene present in all prokaryotes that also contains variable regions that differentiate between species.
Performance and Application of 16S rRNA Gene Cycle Sequencing …
The 16S rRNA gene is about ∼1,500 nucleotides long (∼1.5 kb, although this is an average and some organisms can have 16S sequences that are shorter or longer) and is part of the 30S small subunit of prokaryotic ribosomes that binds to the Shine-Dalgarno sequence at the 3′ end (36 – 40). 16S rRNA has several functions, including a ...
