What Are Introns and What Is Their Function? - Biology Insights
Aug 14, 2025 · Introns are the non-coding, intervening sequences interspersed within these exons. Think of a gene as a recipe in a cookbook. Exons are the precise, actionable steps and ingredients. …
INTRON Definition & Meaning - Merriam-Webster
Feb 3, 2026 · The meaning of INTRON is a polynucleotide sequence in a nucleic acid that does not code information for protein synthesis and is removed before translation of messenger RNA.

…separating the exons are called introns. Following transcription, these coding sequences must be joined together before the mRNAs can function. The process of removal of the introns and …
Intron - an overview | ScienceDirect Topics
Introns are genomically encoded sequences that are removed from RNA transcripts (spliced), and can either be self-splicing or be spliced by the spliceosome.
