It is called protein synthesis:

mRNA is created in the nucleolus of a cell

the mRNA moves to the surface of the nucleolus

A ribosome in the cell attaches to the mRNA and reads its code

The ribosome travels to the rough endoplasmic reticulum where it secretes its protein

The protein is trapped in a vesicle (bag) and is transported among microtubules by motor proteins

The vesicle moves to the golgi apparatus where the protein is modified

The vesicle takes the modified protein to the cell surface where the vesicle joins the cell membrane and turns inside out releasing its contents to the outside of the cell

Hope this helps :)
