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 are the molecular machines that carry out protein synthesis by linking amino acids together.
Differentiate ribosomes from other organelles listed: the Golgi apparatus modifies and packages proteins, lysosomes digest cellular waste, and mitochondria generate energy.
Conclude that the ribosome is the organelle directly responsible for synthesizing proteins during translation.
