  1. 18S ribosomal RNA

    18 Svedberg S ribosomal RNA abbreviated 18S rRNA is a part of the ribosomal RNA . The S in 18S represents Svedberg units. 18S rRNA is a component of the small eukaryotic ribosomal subunit 40S . 18S rRNA is the structural RNA for the small component of eukaryotic cytoplasmic ribosome s, and thus one of the basic components of all eukaryotic cells. It is the eukaryotic nuclear homologue of 16S ribosomal RNA , which exists only in Prokaryote s. 18S rRNA data is widely used in molecular analysis to reconstruct the evolutionary history of organisms, especially invertebrates, as its slow evolutionary rate makes it suitable to reconstruct ancient divergences. Uses in phylogeny The small subunit SSU 18S rRNA gene is one of the most frequently used genes in phylogenetic studies and an important marker for random target polymerase chain reaction PCR in environmental biodiversity screening. ref name Meyer 2010 In general, rRNA gene sequences are easy to access due to highly conserved flanking regions allowing for the use of universal primer s. ref name Meyer 2010 Their repetitive arrangement within the genome provides excessive amounts of template DNA for PCR, even in smallest organisms.

  1. Ribosomal protein

    A ribosomal protein is any of the protein s that, in conjunction with Ribosomal RNA rRNA , make up the ribosomal subunits involved in the cellular process of translation genetics translation . A large part of the knowledge about these organic molecules has come from the study of Escherichia coli E. coli ribosomes. Most ribosomic proteins have been isolated and specific anti bodies have been produced. These, together with electron microscope electronic microscopy and the use of certain reactives, have allowed for the determination of the topography of the proteins in the ribosome. Proteins in E. coli ribosomes The ribosome of E. coli has about 22 proteins in the small subunit labelled S1 to S22 and 34 proteins in the large subunit L1 to L36 . All of them are different with three exceptions one protein is found in both subunits S20 and L26 , L7 and L12 are acetylated and methylated forms of the same protein, and L8 is a complex of L7 L12 and L10.

This binding event can lower gene expression via a number of mechanisms for example, in the protein bound state, the RNA could form an intrinsic termination intrinsic transcription termination stem loop . When cellular concentrations of the ribosomal protein are not high, they are occupied in the ribosome, and are not available in significant quantities to bind the mRNA leader. This leads to increased expression of the gene, which leads to the synthesis of more copies of the ribosomal protein. Many examples of ribosomal protein leaders are known in bacteria .

  1. Ribosomal binding site

    A ribosomal binding site RBS is a sequence on mRNA that is bound by the ribosome when initiating translation biology protein translation . It can be either the 5 cap of a messenger RNA in eukaryotes , a region 6 7 nucleotides upstream of the start codon AUG in prokaryotes called the Shine Dalgarno sequence , or an internal ribosome entry site IRES in viruses. The sequence is complementary to the 3 end of the rRNA. The ribosome searches for this site and binds to it through base pairing of nucleotides. Then, the ribosome begins the translation process and recruits initiation factors. After finding the ribosome binding site in eukaryotes, the ribosome recognizes the Kozak consensus sequence and begins translation at the 1 AUG codon. genetics stub GeneticTranslation Category Protein biosynthesis Category Molecular biology category drug interaction Category Cell biology ...   more details

  1. Ribosomal Intergenic Spacer analysis

    RRNA Ribosomal RNA rRNA intergenic spacer analysis RISA is a method of microbial community analysis that provides a means of comparing differing environments or treatment impacts without the bias imposed by culture dependent approaches. RISA involves PCR amplification of a region of the rRNA gene operon between the small 16S and large 23S subunits called the intergenic spacer region ISR. By using oligonucleotide primers targeted to conserved regions in the 16S and 23S genes, RISA fragments can be generated from most of the dominant bacteria in an environmental sample. While the majority of the rRNA operon serves a structural function, portions of the 16S 23S intergenic region can encode tRNAs depending on the bacterial species. However the taxonomic value of the ISR lies in the significant heterogeneity in both length and nucleotide sequence. In RISA, we attempt to exploit the length heterogeneity of the ISR, which has been shown to range between 150 and 1500 bp with the majority of the ISR lengths being between 150 and 500 bp. The resulting PCR product will be a mixture of fragments contributed by several dominant community members. This product is electrophoresed in a polyacrylamide gel, and the DNA is visualized following staining. The result is a complex banding pattern that provides a community specific profile, with each DNA band corresponding to a bacterial population on the original assemblage.
