To remove introns and splice exons together, RNA splicing occurs. This sequence is recognized and cut by an enzyme. Right after the pre-mRNA is transcribed, several small nuclear ribonucleoprotein particles (snRNPs) attach to both ends of each intron. Each particle has an RNA component referred to as the snRNA, which work together to ensure the redundant and irrelevant introns don't make it to the ribosome for polypeptide synthesis.
