Question

A simplified model of protein synthesis is shown below.
Process 1 Process 2
DNA----------> mRNA-----------> Protein




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 best response to revise the simplified model of protein synthesis is:

A. Between processes 1 and 2, the mRNA must leave the nucleus.

This is an accurate depiction because in eukaryotic cells, mRNA is synthesized in the nucleus and must exit the nucleus through the nuclear pores to reach the ribosomes in the cytoplasm, where protein synthesis occurs.
