Ribosomal frameshifting , also known as translational frameshifting or translational recoding , is a biological phenomenon that occurs during translation that results in the production of multiple, unique proteins from a single mRNA . [ 1 ] The process can be programmed by the nucleotide sequence of the mRNA and is som... | https://en.wikipedia.org/wiki/Ribosomal_frameshift |
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. [ 1 ] RISA involves PCR amplification of a region of the rRNA gene operon betwe... | https://en.wikipedia.org/wiki/Ribosomal_intergenic_spacer_analysis |
Ribosomal pause refers to the queueing or stacking of ribosomes during translation of the nucleotide sequence of mRNA transcripts. These transcripts are decoded and converted into an amino acid sequence during protein synthesis by ribosomes. Due to the pause sites of some mRNA's, there is a disturbance caused in transl... | https://en.wikipedia.org/wiki/Ribosomal_pause |
In molecular biology , ribosomal s6 kinase ( rsk ) is a family of protein kinases involved in signal transduction . There are two subfamilies of rsk, p90 rsk , also known as MAPK-activated protein kinase-1 (MAPKAP-K1), and p70 rsk , also known as S6-H1 Kinase or simply S6 Kinase . There are three variants of p90 rsk ... | https://en.wikipedia.org/wiki/Ribosomal_s6_kinase |
Ribosomally synthesized and post-translationally modified peptides ( RiPPs ), also known as ribosomal natural products , are a diverse class of natural products of ribosomal origin. [ 1 ] Consisting of more than 20 sub-classes, RiPPs are produced by a variety of organisms , including prokaryotes , eukaryotes , and arch... | https://en.wikipedia.org/wiki/Ribosomally_synthesized_and_post-translationally_modified_peptides |
A ribosome binding site , or ribosomal binding site ( RBS ), is a sequence of nucleotides upstream of the start codon of an mRNA transcript that is responsible for the recruitment of a ribosome during the initiation of translation . Mostly, RBS refers to bacterial sequences, although internal ribosome entry sites (IRES... | https://en.wikipedia.org/wiki/Ribosome-binding_site |
Ribosome biogenesis is the process of making ribosomes . In prokaryotes , this process takes place in the cytoplasm with the transcription of many ribosome gene operons . In eukaryotes, it takes place both in the cytoplasm and in the nucleolus . It involves the coordinated function of over 200 proteins in the synthes... | https://en.wikipedia.org/wiki/Ribosome_biogenesis |
Ribosome profiling , or Ribo-Seq (also named ribosome footprinting ), is an adaptation of a technique developed by Joan Steitz and Marilyn Kozak almost 50 years ago that Nicholas Ingolia and Jonathan Weissman adapted to work with next generation sequencing that uses specialized messenger RNA ( mRNA ) sequencing to dete... | https://en.wikipedia.org/wiki/Ribosome_profiling |
Ribotyping is a molecular technique for bacterial identification and characterization that uses information from rRNA -based phylogenetic analyses. [ 1 ] It is a rapid and specific method widely used in clinical diagnostics and analysis of microbial communities in food, water, and beverages. [ 1 ]

Ribozymes ( ribo nucleic acid en zyme s) are RNA molecules that have the ability to catalyze specific biochemical reactions, including RNA splicing in gene expression , similar to the action of protein enzymes . The 1982 discovery of ribozymes demonstrated that RNA can be both genetic material (like DNA ) and a biologi... | https://en.wikipedia.org/wiki/Ribozyme |
Ribozyviria is a realm of satellite nucleic acids — infectious agents that resemble viruses , but cannot replicate without a helper virus . [ 1 ] Established in ICTV TaxoProp 2020.012D, the realm is named after the presence of genomic and antigenomic ribozymes of the Deltavirus type. The agents in Ribozyviria are satel... | https://en.wikipedia.org/wiki/Ribozyviria |
Ribulose 1,5-bisphosphate ( RuBP ) is an organic substance that is involved in photosynthesis , notably as the principal CO 2 acceptor in plants. [ 1 ] : 2 It is a colourless anion, a double phosphate ester of the ketopentose ( ketone -containing sugar with five carbon atoms) called ribulose . Salts of RuBP can be isol... | https://en.wikipedia.org/wiki/Ribulose_1,5-bisphosphate |
Edith Ulrica Hübbe (10 October 1885 – 15 August 1967), [ 1 ] invariably referred to as Rica Hübbe or Hubbe , was a South Australian medical doctor and teacher.
Samuel Grau "Sam" Hübbe (c. 1848 – 12 September 1900) was the first South Australian commissioned officer to be killed in the Boer War . [ 2 ] A practising Uni... | https://en.wikipedia.org/wiki/Rica_Hübbe |
In computability theory , Rice's theorem states that all non-trivial semantic properties of programs are undecidable . A semantic property is one about the program's behavior (for instance, "does the program terminate for all inputs?"), unlike a syntactic property (for instance, "does the program contain an if-then-els... | https://en.wikipedia.org/wiki/Rice's_theorem |
