splicing

Splicing is a process that happens inside cells to produce the final message, called mRNA, from genetic information stored in DNA. When a gene is transcribed, it creates a long precursor mRNA with both valuable instructions (exons) and non-essential parts (introns). Splicing involves cutting out the introns and joining the exons together, resulting in a mature mRNA molecule that can be used to produce proteins. This process allows a single gene to generate different versions of mRNA, and therefore different proteins, increasing the diversity and adaptability of living organisms.
