Two ribosomal units attach to each other when Mg⁺² ion concentration reaches:
Correct answer: C. 1 mM
- A. 5 mM
- B. 0.02 mM
- C. 1 mM
- D. 0.5 mM
Explanation
1 mM is the threshold concentration at which the ribosomal units can either or detach. Increasing the concentration to 1 mM or higher would allow for the small and large subunits to bind to each other.

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.
