Intron Splicing

Intron splicing is the process by which intervening sequences, called introns, are removed from a transcript before it leaves the nucleus, resulting in the formation of mature mRNA. This process is crucial for the production of functional proteins in eukaryotic cells.

Overview

Intron splicing is a vital process in the maturation of mRNA, where non-coding regions (introns) are removed, and coding regions (exons) are joined together. This process is facilitated by the spliceosome, a complex of proteins and RNA that ensures the accurate removal of introns. Understanding intr...

Key Terms

Intron
A non-coding section of RNA that is removed during splicing.

Example: Intron sequences are not included in the final mRNA.

Exon
A coding section of RNA that remains in the final mRNA after splicing.

Example: Exons are expressed in the final protein product.

Spliceosome
A complex of proteins and RNA that carries out splicing.

Example: The spliceosome recognizes intron-exon boundaries.

Pre-mRNA
The initial RNA transcript that contains both introns and exons.

Example: Pre-mRNA undergoes splicing to become mature mRNA.

Lariat
A loop structure formed during the splicing of introns.

Example: The lariat is released and degraded after splicing.

Alternative Splicing
A process that allows a single gene to produce multiple mRNA variants.

Example: Alternative splicing can lead to different protein isoforms.
