eukarüootsete geenide DNA-aluste vahejärjestused, mida ei esine töödeldud RNA-transkriptis, kuivõrd nad lõigatakse splaissingul primaarsest RNA-transkriptist välja, An intron is any nucleotide sequence within a gene that is removed by RNA splicing while the final mature RNA product of a gene is being generated. 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.
