In eukaryotes, what processing does mRNA undergo before translation?

Explanation:
Eukaryotic mRNA is processed in the nucleus by removing introns and joining exons, producing a mature transcript that also receives a 5' cap and a poly-A tail. This mature mRNA then exits the nucleus and is translated in the cytoplasm. Intron removal with exon joining is essential because introns are noncoding sequences that must be removed to create a continuous coding sequence. Translation in the nucleus doesn’t occur, and splicing happens before export and translation, not after.
