- alternative splicing
Eukaryotic genes are composed of exons and introns, the latter being removed by RNA splicing before transcribed mRNA leaves the nucleus. Commonly, a single gene can encode several different mRNA transcripts, caused by cell- or tissue-specific combination of different exons. This is known as alternative splicing.
