Responses A Between processes 1 and 2, the mRNA must leave the nucleus.Between processes 1 and 2, the mRNA must leave the nucleus. B Prior to process 1, DNA should copy itself to allow the cell to divide.Prior to process 1, DNA should copy itself to allow the cell to divide. C After process 2, the completed protein should travel back to the nucleus.After process 2, the completed protein should travel back to the nucleus. D During process 2, the ribosome should remove any mutated nucleotides from the mRNA.

To revise the simplified model of protein synthesis for a more accurate depiction, the best choice is:
**A. Between processes 1 and 2, the mRNA must leave the nucleus.**
This response correctly highlights the important step where mRNA, after being transcribed from DNA in the nucleus, must exit the nucleus and enter the cytoplasm to be translated into a protein by ribosomes. The other options either do not pertain to the direct processes of protein synthesis or misrepresent fundamental aspects of the cellular processes involved.
