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.
The nucleic acid sequence in the DNA, or RNA transcript following genetic splicing. Supplement. Genes contain exons which are regions coding for proteins and which are interrupted by the unused sequences called introns. Exons have been found to include both sequences coding for amino acids and untranslated sequences. The introns are removed and the exons are joined together to form the final functional mRNA. Related forms: exonic (adjective). Compare: intron. See also: DNA, RNA, translation, mRNA, protein synthesis.
