Subheadings: WebSep 1, 2024 · Cryptic splice site Splicing occurs at the 5′ and 3′ ends of intronic regions of the precursor messenger RNA s (pre-mRNA), which are known as 5′ and 3′ splice sites. The splicing is promoted by a spliceosome complex which recognizes the exon-intron boundaries and removes the intron with single nucleotide precision.
