      Pre-mRNA splicing is a key step for generating mature protein-coding mRNA. An RNA protein complex known as the spliceosome carries out the chemistry of pre-mRNA splicing. However, several pre- spliceosomal intermediates are assembled on the pre-mRNA before the formation of the catalytically acti-vated spliceosome.

      • In eukaryotes, mRNA is synthesized in the nucleus from pre-messenger RNA (pre-mRNA) molecules, and then shipped to the cytoplasm, where translation occurs • RNA processing (or post-transcriptional modification) refers to the molecular mechanisms that lead to the production of mRNA from pre-mRNA.

      splicing is the process of removing introns from the pre-mRNA, and joining the exons together to form a mature mRNA. Alternative splicing, on the other hand, is the process where exons can be included or excluded in different combi-nations to create a diverse array of mRNA transcripts from a single pre-mRNA and therefore serves as a process to ...

      RNA processingrefers to any covalent modification to the RNA that occurs after transcription. This includes specific cleavage, addition of nucleotides, methylation or other modification of the nucleotides, and removal of introns by splicing. 2.

      the biogenesis of mRNA isoforms by alternative splicing. T he production of mRNA in eukaryoticcells involves precursor mRNA (pre-mRNA) synthesis and processing—in particular, 5′ end capping, splicing, and 3′ end cleavage and polyadenylation. During splicing, noncoding introns are pre-dominantly removed from the pre-mRNA in
