Understand the process of translation in cell biology, 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 other organelles like the Golgi apparatus, peroxisomes, and lysosomes have different functions unrelated to the direct synthesis of proteins.
Conclude that the ribosome is the organelle directly responsible for protein synthesis during translation.
