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

Prior to process 1, DNA should copy itself to allow the cell to divide

After process 2, the completed protein should travel back to the nucleus

Between processes 1 and 2, the mRNA must be modified before leaving the

nucleus

During process 2, the ribosome should remove any mutated nucleotides

from the mRNA

The correct answer is: Between processes 1 and 2, the mRNA must be modified before leaving the nucleus

Explanation:

Protein synthesis begins with the process of transcription, which takes place in the nucleus. Here, DNA is copied into mRNA. Next, the mRNA is processed or modified and then exported to cytoplasm and where the process of translation takes place. This modification of mRNA is important as it transforms into a mature mRNA. The three main modifications that a mRNA, in the nucleus, undergoes are:
