An intron is any nucleotide sequence within a gene that is not expressed or operative in the final RNA product. The word intron is derived from the term intragenic region, i.e., a region inside a gene.[1] The term intron refers to both the DNA sequence within a gene and the corresponding RNA sequence in RNA transcripts.[2] The non-intron sequences that become joined by this RNA processing to form the mature RNA are called exons.[3]
Introns are found in the genes of most eukaryotes and many eukaryotic viruses and they can be located in both protein-coding genes and genes that function as RNA (noncoding genes). There are four main types of introns: tRNA introns, group I introns, group II introns, and spliceosomal introns (see below). Introns are rare in Bacteria and Archaea (prokaryotes).
