Splicing (genetics)

... gene often contains altering sequences known as exons (expressed codons) and introns (interrupting co...ed pre-mRNA that is composed of both introns and exons (see transcription ). Pre-mRNA has to be spliced before it can be translated into protein. Duri...

Spliceosome

...a between these locations is removed, and the two exons are spliced together. Alternative splicing Alternative splicing (the re-combination of different introns ) is a major source of genetic diversity in eukaryotes.For example alternative splicing is what makes our immune systems so diver...

Lipase

...eview of reported mutations: 75 % are clustered in exons 5 and 6. Ann Genet. 44(1):25-32. Girod, A., C. E. Wobus, Z. Zadori, M. Ried, K. Leike, P. Tijssen, J. A. Kleinschmidt, and M. Hallek. 2002. The VP1 capsid protein of adeno-associated virus type 2 is carrying a phospholipase A2 domain required for vi...

Intron

...a gene that remain in the spliced mRNA are called exons . Introns sometimes allow for alternative splicing of a gene, so that several different proteins that share some sections in common can be produced from a single gene. The control of mRNA splicing, and hence of which alternative is produced, is p...

Gene

...splice the transcripts of a gene, by keeping the exons and removing the introns . So, the DNA strand needs to be in an exon to be expressed. Because of the complexity of the splicing process, one transcribed RNA may be spliced in alternate ways to produce not one but a variety of proteins ( alternati...

Alternative splicing

...from the DNA , it includes several introns and exons . In nematodes , the mean is 4-5 exons and introns; in the fruit fly Drosophila there are more than 100 introns and exons in one transc...
