Explanation:

5' capping occurs on the primary transcript which is significant and preventing the RNA from being a target of exonucleases. Splicing of precursor RNA is used to remove introns (non-coding regions) to form a mature mRNA that can be exported from the nucleus to be translated by ribosomes in the cytoplasm.
