Answer:
Transcription, 5' cap addition, addition of poly-A tail, exon splicing, passage through nuclear membrane
Explanation:
After being synthesized during the transcription, mRNA (pre-mRNA) must be modified in order to be functional (mature mRNA) and exported from the nucleus for the process of translation.Modification of pre-mRNA include:
Modified mRNA can now be transported from the nucleus into the cytoplasm.
