Intron
A transcribed region removed from many eukaryotic RNA precursors during RNA splicing.
Overview
EXPLORE BY LEVELAn intron is copied into an early RNA message but is removed during splicing in many eukaryotic genes. Introns are not simply useless: they can contain control sequences and influence how an RNA is processed.

Intron content and processing vary among genes and organisms. Splicing is coupled to transcription and regulated by splice sites, RNA structure, and RNA-binding proteins; not every transcript follows one canonical pattern.
