WebNov 29, 2024 · Introns are an ancient feature found across all eukaryotic life, a wide range of organisms that spans all animals, plants, fungi, and protists, but are absent in prokaryotic genomes such as those of bacteria. There is a massive variation in the number of introns found in different species’ genomes, even between closely related species. WebIntrons can interrupt the reading frame of a gene by inserting a sequence between two consecutive codons (phase 0 introns), between the first and second nucleotide of a codon (phase 1 introns), or between the second and third nucleotide of a codon (phase 2 introns).
