The correct answer is "protein making and protein packaging".
To identify the correct answer choice, let's first understand the functions of the rough endoplasmic reticulum and Golgi apparatus in the protein synthesis and transportation process.
The rough endoplasmic reticulum (RER) is responsible for protein synthesis. It consists of ribosomes attached to its surface, which are responsible for building proteins using the information encoded in DNA. These proteins are synthesized and released into the lumen of the RER.
The Golgi apparatus, on the other hand, is involved in protein packaging and transportation. It receives these newly synthesized proteins from the RER and modifies, sorts, and packages them into transport vesicles. These vesicles then transport the proteins to different parts of the cell or outside the cell via exocytosis.
Based on this information, the correct answer choice is "protein making and protein packaging." The RER is involved in protein synthesis, while the Golgi apparatus is responsible for protein packaging and transportation.
