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 ().It works by removing all the introns (non-coding regions of RNA) and splicing back together exons (coding regions).
Alternative splicing, alternative RNA splicing, or differential splicing, is an alternative splicing process during gene expression that allows a single gene to produce different splice variants. For example, some exons of a gene may be included within or excluded from the final RNA product of the gene. [ 1 ]

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 ...
As a part of the maturation process, RNA splicing removes the non-coding RNA introns leaving behind the exons, which are then spliced and joined together to form the mature mRNA. [3] [8] Splicing is conducted by the spliceosome. The spliceosome is a large ribonucleoprotein which cleaves the RNA at the splicing site and recombines the exons of ...
Trans-splicing is a special form of RNA processing where exons from two different primary RNA transcripts are joined end to end and ligated. It is usually found in eukaryotes and mediated by the spliceosome , although some bacteria and archaea also have "half-genes" for tRNAs .
A short 20-nucleotide RNA variant ribozyme was identified that self-reproduces via template directed ligation of two 10 nucleotide oligomers. [38] This minimal kind of RNA self-reproduction was discovered in a random pool of oligmers, and may represent an early step in the emergence of an RNA based genetic system from primordial components. [38]
An exon junction complex (EJC) is a protein complex which forms on a pre-messenger RNA strand at the junction of two exons which have been joined together during RNA splicing. The EJC has major influences on translation, surveillance, localization of the spliced mRNA, and m 6 A methylation.
