What cellular organelle is the site of protein synthesis?

Explanation:
Protein synthesis is carried out by ribosomes, the cellular machines that translate mRNA into polypeptides. Ribosomes can be free in the cytoplasm or attached to the rough endoplasmic reticulum, and they read the genetic code in messenger RNA to link amino acids in the exact order needed to form a protein. The nucleus stores the DNA and is the site of transcription, producing mRNA that must be exported to the cytoplasm for translation. Lysosomes are involved in digestion and recycling, while mitochondria have their own protein-synthesis machinery for certain mitochondrial proteins but are primarily focused on energy production. The ribosome is the key site where the actual assembly of proteins from amino acids occurs.
