Intron - Definition, Function and Structure Biology …

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.

Introns are sequences of RNA that don’t contain any information about how to construct a protein. … WebThe exons are then spliced together to form the mature, protein coding RNA. While they don't code for protein, introns do have a lot of important functions including regulating how fast RNA can mature or be degraded. Introns are also super important in the context of evolution, as they allow recombination of gene elements.
