RNA processing continues with the removal of portions of the coding segment that do not actually code for protein. This process is carried out by small RNA molecules. These small RNA molecules join with other proteins to form spliceosomes. (For simplicity, only one spliceosome is shown here.) Spliceosomes delete portions of the RNA called introns. They then connect the remaining segments, which are called exons, to form a finished mRNA molecule. The mRNA leaves the nucleus and enters the cytoplasm, where translation of the RNA message into protein occurs.
