Intron excision
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). For nuclear … See more Several methods of RNA splicing occur in nature; the type of splicing depends on the structure of the spliced intron and the catalysts required for splicing to occur. Spliceosomal complex Introns See more Spliceosomal splicing and self-splicing involve a two-step biochemical process. Both steps involve transesterification reactions that occur between RNA nucleotides. tRNA … See more The process of splicing is linked with HIV integration, as HIV-1 targets highly spliced genes. See more Splicing events can be experimentally altered by binding steric-blocking antisense oligos, such as Morpholinos or Peptide nucleic acids to … See more Splicing occurs in all the kingdoms or domains of life, however, the extent and types of splicing can be very different between the major … See more In many cases, the splicing process can create a range of unique proteins by varying the exon composition of the same mRNA. This phenomenon is then called alternative splicing. Alternative splicing can occur in many ways. Exons can be extended or … See more DNA damage affects splicing factors by altering their post-translational modification, localization, expression and activity. Furthermore, DNA damage often disrupts splicing by interfering with its coupling to transcription. DNA damage also has an impact on the … See more WebAngiosperm mtDNAs are the largest and least gene-dense genomes among eukaryotes . mRNA production and expression in land plant mitochondria involve extensive processing steps, which include endonucleolytic RNA cleavages, 5′ and 3′ mRNA trimming, extensive sequence editing and, relevantly to our study, the removal of intron (mostly group II …
