Question
A simplified model of protein synthesis is shown below.
How might this model be revised to show a more accurate depiction of protein synthesis?
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.

The most accurate revision of the simplified model of protein synthesis would be:
**A**: Between processes 1 and 2, the mRNA must leave the nucleus.
This option correctly highlights the important step in protein synthesis where mRNA, after being transcribed from DNA in the nucleus, must exit the nucleus to reach the ribosome in the cytoplasm to undergo translation into a protein. The other options either introduce inaccuracies or unrelated processes.
