• B. Protein synthesis
• C. DNA replication
• D. Energy production

Answer: (A)

Verified step by step guidance

1. Understand that the Golgi apparatus is an organelle found in eukaryotic cells, which are cells with a defined nucleus.
2. Recognize that the primary role of the Golgi apparatus is related to proteins, which are synthesized in the rough endoplasmic reticulum (ER) and then transported to the Golgi apparatus.
3. Learn that within the Golgi apparatus, proteins undergo further modifications. These modifications can include glycosylation, where sugars are added to proteins, and other chemical changes that are necessary for the protein's final function.
4. After modification, the Golgi apparatus packages these proteins into vesicles. These vesicles are small, membrane-bound sacs that transport the proteins to their final destinations inside or outside the cell.
5. Differentiate the function of the Golgi apparatus from other cellular processes such as DNA replication, which occurs in the nucleus, and energy production, which primarily occurs in the mitochondria.
