A pre mRNA is shown in the image below Before the mRNA can leave the nucleus there are other modifications that must be made A 5 cap and poly A tail must be added to the correct ends of the pre mRNA CFTR A diagram of CFTR mRNA A B 1 2 C D 12 13 14 Which of the following best describes what would happen if the 5 methyl guanosine cap was not added to an pre mRNA 15 16 HAH 26 27 The mRNA molecule would not be able to add the poly A tail on its strand at the 5 end The transcript would degrade when the mRNA moves out of the nucleus to the cytoplasm The mRNA molecule would move out of the nucleus and create more copies of the mRNA molecule The mRNA molecule would stabilize and start the process of translation within the nu cleus of the cell
