May 8, 2022 · RNA splicing is a form of RNA processing in which a newly made precursor messenger RNA (mRNA) is transformed into a mature RNA by removing the non-coding sequences termed introns. The process of RNA splicing involves the removal of non-coding sequences or introns and joining of the coding sequences or exons.
During transcription, eukaryotic cells transcribe the whole gene (all introns and exons) to produce pre-mRNA molecules. pre-mRNA contains the introns and exons of a certain gene. Before the pre-mRNA exits the nucleus, splicing occurs: The non-coding sections are removed. The coding sections are joined together.

- That was a mistake! Thank you for noticing and pointing it out. It should be fixed now :)
- Lim Pin Seng, Introns allow for alternative splicing; generating multiple proteins from a single gene. It adds a layer of complexity to an organism...
- I think they are only considered "junk" in terms of what they contribute to the resultant protein. They do likely play a role in regulation, but be...
- I am not aware of that but sounds interesting! That is interesting point of view because Prokaryotes do not have introns (and can't because of coup...
- Good question! Control of alternative splicing is very complex — it often involves binding of proteins or small RNAs to the pre-mRNA in ways that f...
- After transcription of a eukaryotic pre-mRNA, its introns are removed by the spliceosome, joining exons for translation. The intron products of spl...
- Prokaryotes do have some post-transcriptional modifications, but introns are much less common and as far as I know are always self-splicing — i.e....
- Correct! Nice work :)
Oct 31, 2023 · Alternative splicing allows more than one protein to be produced from a gene and is an important regulatory step in determining which functional proteins are produced from gene expression. Thus, splicing is the first stage of post-transcriptional control.
RNA splicing is a process in molecular biology where a newly-made precursor messenger RNA (pre- mRNA) transcript is transformed into a mature messenger RNA (mRNA). It works by removing all the introns (non-coding regions of RNA) and splicing back together exons (coding regions).
Jun 14, 2012 · Lariats are discarded byproducts of RNA splicing, the process by which genetic instructions for making proteins are assembled. A new study has found hundreds more lariats than ever before, yielding new information about how splicing occurs and how it can lead to disease.
Splicing of a pre-mRNA molecule occurs in several steps that are catalyzed by small nuclear ribonucleoproteins (snRNPs). After the U1 snRNP binds to the 5′ splice site, the 5′ end of the intron...
