Understand the process of translation in eukaryotic cells, which is the synthesis of proteins from messenger RNA (mRNA).
Recall that translation occurs in the cytoplasm where ribosomes read the mRNA sequence to assemble amino acids into a polypeptide chain.
Identify the organelle responsible for this process: ribosomes, which can be free-floating in the cytoplasm or attached to the rough endoplasmic reticulum.
Recognize that mitochondria are involved in energy production, lysosomes in degradation of cellular waste, and the Golgi apparatus in modifying and packaging proteins, but none directly synthesize proteins.
Conclude that the ribosome is the primary organelle responsible for protein synthesis during translation in eukaryotic cells.
