WebAlong the length of the mRNA, there is an alternating pattern of exons and introns: Exon 1 - Intron 1 - Exon 2 - Intron 2 - Exon 3. Each consists of a stretch of RNA nucleotides. During splicing, the introns are revmoved … 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).
