This step occurs by transesterification; in this case, an OH group at the 3′ end of the exon attacks the phosphodiester bond at the 3′ splice site. The adjoining exons are covalently bound ...

What's the difference between mRNA and pre-mRNA? It's all about splicing of introns. See how one RNA sequence can exist in nearly 40,000 different forms.

According to the researchers, recognizing splice sites computationally is a crucial step in accurately assembling gene transcripts in modern genetics studies, where RNA sequencing experiments ...
