Question

Quizplus · Accepted Answer

RNA splicing involves two transesterification reactions, where the 2'-OH of a specific adenosine in the intron attacks the 5' splice site, and then the newly formed 3'-OH of the exon attacks the 3' splice site, ligating the exons together and releasing the intron.
