Sign in to saveAlso known as introns
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. The term intron refers to both the DNA sequence within a gene and the corresponding RNA sequence in RNA transcripts. The non-intron sequences that become joined by this RNA processing to form the mature RNA are called exons.
An intron is a section of DNA within a gene that gets removed during the process of creating RNA, so it doesn't end up in the final RNA product that cells use. Scientists study introns because understanding how they're removed and how genes are processed helps explain how genetic information is actually used to make proteins and direct cellular functions.
