Each ribosome consists of:
Correct answer: D. Two subunits
- A. Five subunits
- B. Four subunits
- C. Three subunits
- D. Two subunits
Explanation
Ribosomes are essential organelles in the process of protein synthesis, consisting of two subunits: the large subunit and the small subunit. These subunits are crucial as they come together to form a functional ribosome capable of translating mRNA into a polypeptide chain. Options suggesting more than two subunits are incorrect because the ribosomal structure does not include additional subunits.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
