What are the steps in order that occur as protein is synthesized within a and finally excreted for use outside the cell?

Protein synthesis begins with transcription, where DNA is converted into messenger RNA (mRNA) in the nucleus. The mRNA then travels to the ribosome in the cytoplasm, where translation occurs, and amino acids are assembled into a polypeptide chain based on the mRNA sequence. After synthesis, the protein may undergo post-translational modifications in the endoplasmic reticulum and Golgi apparatus. Finally, the mature protein is packaged into vesicles and excreted from the cell through exocytosis for use outside the cell.
