WebRNA splicing is the process by which the newly synthesized pre-mRNA, also known as hnRNA, (heterogeneous nuclear RNA) is processed and forms the mature mRNA. hnRNA … WebSplicing involves the removal of introns and joining of exons in a specific order. Tailing involves the addition of about two to three hundred adenylate residues to the three prime end of the hnRNA in a template-independent manner, giving rise to a poly A tail. This process is also known as polyadenylation.

WebIntrons are removed from hnRNA by the process of splicing to create functional mRNAs which comprise just the exon sequences of the gene in question. Several different mRNAs can, in principle, be derived from a single hnRNA primary transcript through the process of alternative splicing. WebWhy do we splice introns? RNA splicing is a process that removes the intervening, non-coding sequences of genes (introns) from pre-mRNA and joins the protein-coding sequences (exons) together in order to enable translation of mRNA into a protein.. What is the purpose of introns in DNA? Introns, from this perspective, have a profound purpose.
