What are introns?
Quick Answer
Introns are sections of a gene that are transcribed into RNA but removed before a protein is made. The remaining pieces, called exons, are stitched together.
The Full Story
Introns are non-coding segments within many eukaryotic genes. When a gene is copied into pre-mRNA, both introns and exons are included at first, but the cellβs splicing machinery removes the introns. This process allows one gene to produce different protein variants through alternative splicing. Introns are common in human genes and are an important part of how gene expression is regulated.
Key Facts
1.Introns are removed during RNA splicing
2.Exons are the coding segments kept in mature RNA
3.Alternative splicing can create multiple proteins from one gene
