Splicing refers to the removal of non-coding regions (introns) from pre-mRNA molecules and joining together of coding regions (exons) to produce mature mRNA.
Related terms
Intron: Non-coding regions within pre-mRNA that are removed during splicing.
Exon: Coding regions within pre-mRNA that are retained after splicing and carry instructions for protein synthesis.
Pre-mRNA: The initial transcript produced during transcription, which contains both introns and exons.
