KnowraIntronLinked fromLinked fromThe 8 pages that link to Intron, each with the reason it gives.All 8Broader topic 3Related 3Compared with 2Alternative splicingRelated: Alternative splice choices determine which intron boundaries are used or retained.RNA splicingBroader topic: Splicing excises introns while retaining the RNA segments that encode the joined message.ExonCompared with: Introns are excised, unlike exons retained in mature RNA.PseudogeneRelated: Their presence or absence helps distinguish duplicated from processed pseudogenes.Complementary DNACompared with: Introns are generally absent from cDNA made from mature messenger RNA.Walter GilbertRelated: Gilbert’s intron early hypothesis treated introns as ancient features of gene architecture.Protein isoformBroader topic: Introns provide boundaries where alternative splice choices can be made.Non-coding DNABroader topic: They are a widespread class of non-coding DNA embedded within protein-coding genes.
