Final answer:
The synthesis and post-translational processing of a protein begins with transcription in the nucleus, followed by translation on the ribosome, modification in the rough endoplasmic reticulum, packaging in the Golgi apparatus, and finally transportation to its destination in or outside of the cell.
Step-by-step explanation:
Protein Synthesis and Post-Translational Processing
To trace the synthesis and post-translational processing of a protein, we need to order the different choices provided:
- d. The gene encoding the protein is found within the DNA in the nucleus and is transcribed into mRNA which exits the nucleus through pores.
- a. The protein is assembled during translation of the mRNA on ribosomes located on the surface of the rough endoplasmic reticulum (RER).
- c. Modification and temporary storage of a protein may occur in the rough endoplasmic reticulum.
- e. Transitional vesicles carry the protein from the endoplasmic reticulum to the Golgi apparatus. The Golgi apparatus prepares and packages the protein for transport to its final destination.
- b. Condensing vesicles transport the protein to its ultimate destination within the cell or secretory vesicles transport the protein to the cell surface for export.
The above steps outline the journey of a protein from its genetic blueprint in the DNA up to its functional form and delivery to its operative location within or outside the cell.
