The term intron refers to both the DNA sequence within a gene and the corresponding sequence in the unprocessed RNA transcript. As part of the RNA processing pathway, introns are removed by RNA splicing either shortly after or concurrent with transcription. Introns are found in the genes of most organisms and many viruses.
2. Removal of introns from mRNA precursors and the reattachment or annealing of exons. Synonym(s): RNA splicing. 3. Posttranslational modification of a protein involving two proteolytic enzymes and one ligation; results in the removal of an internal sequence of amino acyl residues.
