Final answer:
Splicing is used to remove introns from an RNA gene sequence. Spliceosomes recognize specific sequences at the ends of the intron and cut the RNA transcript at those points. The exons are then joined together to create a translatable mRNA molecule.
Step-by-step explanation:
The process of removing introns from an RNA gene sequence is called splicing. Splicing is catalyzed by protein complexes called spliceosomes, which are composed of proteins and RNA molecules called small nuclear RNAs (snRNAs). Spliceosomes recognize sequences at the 5' and 3' ends of the intron and cut the RNA transcript at those points. The exons, which are the coding sequences, are then joined together for ligation to generate a translatable mRNA molecule.
