Which of the following is the site of translation in a eukaryotic cell?

• A. Endoplasmic reticulum
• B. Golgi apparatus
• C. Nucleus
• D. Ribosome

Answer: (D)

Verified step by step guidance

1. Understand the process of translation: Translation is the process by which ribosomes synthesize proteins using messenger RNA (mRNA) as a template.
2. Identify the role of ribosomes: Ribosomes are the cellular structures where translation occurs. They read the sequence of mRNA and assemble amino acids into a polypeptide chain, forming proteins.
3. Distinguish between cellular organelles: The endoplasmic reticulum is involved in protein folding and transport, the Golgi apparatus modifies and packages proteins, and the nucleus houses the cell's DNA and is the site of transcription, not translation.
4. Recognize the location of ribosomes: In eukaryotic cells, ribosomes can be found floating freely in the cytoplasm or attached to the rough endoplasmic reticulum, but the site of translation is specifically the ribosome itself.
5. Conclude that the ribosome is the correct answer: Based on the understanding of translation and the function of ribosomes, the ribosome is the site of translation in a eukaryotic cell.
