Definition
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.
Summary
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 intron splicing is crucial for grasping how genes are expressed and regulated in living organisms. Moreover, intron splicing has significant implications in biotechnology and medicine, particularly in gene therapy and the study of genetic diseases. Errors in splicing can lead to various disorders, emphasizing the importance of this process in maintaining cellular function and health. As we explore further, we can see how alternative splicing contributes to protein diversity and the complexity of gene regulation.
