Trans-splicing is characterized by the joining of two separate exons transcribed RNAs. The signal for this splicing is the outron at the 5’ end of the mRNA, in the absence of a functional 5’ splice site upstream. When the 5’ outron in spliced, the 5’ splice site of the spliced leader RNA is branched to the outron and forms an ...
RNA splicing. RNA splicing is a process in molecular biology where a newly-made precursor messenger RNA (pre- mRNA) transcript is transformed into a mature messenger RNA (mRNA). It works by removing all the introns (non-coding regions of RNA) and splicing back together exons (coding regions). For nuclear-encoded genes, splicing occurs in the ...
Riboswitch. In molecular biology, a riboswitch is a regulatory segment of a messenger RNA molecule that binds a small molecule, resulting in a change in production of the proteins encoded by the mRNA. [1][2][3][4] Thus, an mRNA that contains a riboswitch is directly involved in regulating its own activity, in response to the concentrations of ...
Alternative splicing produces three protein isoforms. Protein A includes all of the exons, whereas Proteins B and C result from exon skipping. Alternative splicing, or alternative RNA splicing, or differential splicing, is an alternative splicing process during gene expression that allows a single gene to produce different splice variants.
Alternative splicing is a phenomenon through which one RNA transcript can yield different protein products based on which segments are considered "introns" and "exons" during a splicing event. [5] Although not specific to humans, it is a partial explanation for the fact that humans and other much simpler species (such as nematodes) have similar ...
Fields. Personalized medicine. Category. v. t. e. RNA editing (also RNA modification) is a molecular process through which some cells can make discrete changes to specific nucleotide sequences within an RNA molecule after it has been generated by RNA polymerase. It occurs in all living organisms and is one of the most evolutionarily conserved ...
RNA-Seq data has been used to infer genes involved in specific pathways based on Pearson correlation, both in plants [129] and mammals. [130] The main advantage of RNA-Seq data in this kind of analysis over the microarray platforms is the capability to cover the entire transcriptome, therefore allowing the possibility to unravel more complete ...
Genetics. In biology, translation is the process in living cells in which proteins are produced using RNA molecules as templates. The generated protein is a sequence of amino acids. This sequence is determined by the sequence of nucleotides in the RNA. The nucleotides are considered three at a time.
