WebDec 20, 2024 · These cryptic splicing events are inclusion of a cryptic exon embedded deep within an intron; selection of cryptic 5ʹ and 3ʹ splice sites; and aberrant recognition of cryptic splice sites within an exon, leading to the interior of this exon being aberrantly recognized as an intron (in a cryptic splicing event known as an exitron). WebMay 25, 2024 · We hypothesized that the EJC, recruited to the exon 13/14 junction, suppresses the cryptic 5’ SS on exon 14 and activates the canonical 5’ SS during removal of intron 14. We tested this using a minigene reporter consisting of exon 14 (containing the cryptic 5’ SS) and its immediately flanking introns and exons (Fig 3D, genomic).

The term i… WebAug 6, 2024 · Intron Structure In general, introns are much longer than exons; they can make up as much as 90% of a gene and can be over 10,000 nucleotides long. Introns are prevalent in genes; over 90% of human genes contain introns with an average of nine introns per gene.

WebApr 25, 2024 · Introns and exons are similar because they are both part of the genetic code of a cell but they are different because introns are non-coding while exons code for proteins.
