Web7 apr. 2024 · Precursor mRNA (pre-mRNA) splicing is the processing step in the gene expression pathway that involves the removal of intronic sequences and ligation of exonic sequences to form mature RNAs (mRNAs). This process is carried out by the spliceosome, a complex molecular machinery that needs to be re-assembled de novo for every … WebOne notable difference, however, is that eukaryotic RNA polymerase associates with mRNA processing enzymes during transcription so that processing can proceed quickly after the start of transcription. The short-lived, unprocessed or partially processed, product is termed pre-mRNA; once completely processed, it is termed mature mRNA.

WebThe pre-mRNA has to go through some modifications to become a mature mRNA molecule that can leave the nucleus and be translated. These include splicing, capping, and addition of a poly-A tail, all of which can potentially be regulated – sped up, slowed down, or altered to result in a different product. Alternative splicing Web3' Processing: The pre-mRNA processing at the 3' end of the RNA molecule involves cleavage of its 3' end and then the addition of about 200 adenine residues to form a poly(A) tail. As the poly(A) tails is synthesised, it binds multiple copies of poly(A) binding protein, which protects the 3'end from ribonuclease digestion.
