noun
- a segment of DNA or RNA that is removed during gene processing and does not code for proteins
Usage: biology; genetics
Examples
- The introns were spliced out during mRNA processing.
- Scientists discovered that this gene contains five introns and six exons.
- Intron removal is essential for proper protein synthesis.
- The mutation occurred within an intron sequence.
- Alternative splicing can include or exclude certain introns.
- Introns are typically much larger than exons in human genes.
