A simplified model of protein synthesis is shown here. How might this model be revised to show a more accurate depiction of protein synthesis?
A) Prior to process 1, DNA should copy itself to allow the cell to divide.
B) After process 2, the completed protein should travel back to the nucleus.
C) Between processes 1 and 2, the mRNA must be modified before leaving the nucleus.
D) During process 2, the ribosome should remove any mutated nucleotides from the mRNA.
