Splicing

Definition

Splicing is the process where introns (non-coding regions) are removed from pre-mRNA and exons (coding regions) are joined together to form mature mRNA ready for translation.

Alternative Splicing:

A regulated process during gene expression that results in a single gene coding for multiple proteins by selectively including or excluding certain exons.

Pre-mRNA: It's an immature single strand of messenger ribonucleic acid. Pre-mRNA is synthesized from a DNA template in the cell nucleus by transcription.

mRNA Processing: The modifications that a primary RNA transcript undergoes before it becomes mature mRNA.
