Final answer:
Splicing is the process by which the intron is released after the lariat is formed. Spliceosomes, complexes of proteins and RNA molecules, recognize the ends of the intron, cut the pre-mRNA, and join the exons together for translation.
Step-by-step explanation:
After the lariat is formed, the intron is released through a process called splicing. Splicing is carried out by a complex of proteins and RNA molecules called spliceosomes. The spliceosome recognizes the ends of the intron, cuts the pre-mRNA at those points, and brings the exons (coding regions) together for ligation, forming a continuous mRNA ready for translation.
