Which of these processes occur before export of a newly transcribed mRNA from the nucleus in eukaryotes?
Show answer and explanation
Correct answer: 5' capping, intron splicing, and polyadenylation
Before export to the cytoplasm, eukaryotic pre-mRNA undergoes 5′ capping, intron splicing, and 3′ poly-A tail addition to become mature mRNA. Only mature mRNA can be exported and translated.
