Answer:
answer( b)
Explanation:
Left panel: eukaryotic cell. In the nucleus, a pre-mRNA is produced through transcription of a region of DNA from a linear chromosome. This transcript must undergo processing (splicing and addition of 5' cap and poly-A tail) while it is still in the nucleus in order to become a mature mRNA.
