Step 2: The oH of the 5. exon attacks the phosphoryl group at the 3, splice site. As a consequence, the 5' and 33 exons are joined and the intron is liberated in the shape of a lariat
Step 2: The OH of the 5’ exon attacks the phosphoryl group at the 3’ splice site. As a consequence, the 5’ and 3’ exons are joined and the intron is liberated in the shape of a lariat
