1. The nucleus revived the signal to make the protein.
2. The DNA message for that protein was copied into a small , signal-stranded copy of DNA called messenger RNA or mRNA for short.
3.mRNA left through the nucleus through the nuclear pores.
4. The mRNA were delivered to the ribosomes which "read" the message and turned it to protein.
5. Then the protein entered the endoplasmic reticulum (ER).
6. A vesicle formed at the end of the ER and carried the protein to the Golgi body.
7. Then the Golgi body packaged the protein and got it ready for transportation.
8. A vecicle formed off the end of the Golgi body and carried that protein to the cell membrane.
9. A vesicle attached to the cell membrane and then then the protein was released out of the cell.
Here's an overall picture of what happened
