spliceosome
rna splicing, in molecular biology, is a form of rna processing in which a newly made precursor messenger rna (pre-mrna) transcript is transformed into a mature messenger rna (mrna). during splicing, introns(non-coding regions) are removed and exons(coding regions) are joined together. for nuclear-encoded genes, splicing takes place within the nucleus either during or immediately after transcription. for those eukaryotic genes that contain introns, splicing is usually required in order to create an mrna molecule that can be translated into protein. for many eukaryotic introns, splicing is carried out in a series of reactions which are catalyzed by the spliceosome, a complex of small nuclear ribonucleo proteins (snrnps). self-splicing introns, or ribozymes capable of catalyzing their own excision from their parent rna molecule, also exist.
rna splicing
an intron is any nucleotide sequence within a gene that is removed by rna splicing during maturation of the final rna product. the word "intron" is derived from the term "intragenic region", i.e. a region inside a gene. the term "intron" refers to both the dna sequence within a gene and the corresponding sequence in rna transcripts. sequences that are joined together in the final mature rna after rna splicing are exons. introns are found in the genes of most organisms and many viruses, and can be located in a wide range of genes, including those that generate proteins, ribosomal rna (rrna), and transfer rna (trna). when proteins are generated from intron-containing genes, rna splicing takes place as part of the rna processing pathway that follows transcription and precedes translation.
