Eukaryotic mRNA molecules contain both exons (coding regions) and introns (non-coding regions). Before leaving the nucleus and being translated into protein, the introns are spliced out of the mRNA molecule by a process called RNA splicing. The resulting mRNA molecule contains only exon sequences, and can be translated by ribosomes. This process is called mRNA processing.
