... 7. The polypeptide chain grows until tRNA reaches 1 of the 3 stop codons (UGA, UAA, UAG). At the end of translation, the protein is released, folded into a 3D structure, transported in a vesicle to the Golgi Apparatus to be modified and “shipped” to its final destination within the cell or outside ...
